45° CV for Lifted Trucks & Jeeps
JE Reel’s new 45-degree CV is built for extreme-lift trucks and Jeeps that need more driveline angle, more suspension travel, and a stronger CV than standard 32-degree units. Production is underway, with availability expected in the first half of December.
Built for Extreme Lifts
Most competing CVs operate at roughly 32 degrees. That works for many builds, but extreme lifts with long-travel coilovers and 12–16 inches of down travel can exceed the CV’s usable angle.
The JE Reel 45° CV gives lifted Jeep and truck owners the additional operating angle needed to use their suspension fully—without relying on limit straps to protect the driveline.
Forged Chrome-Moly Strength
JE Reel’s 45° CV is made from forged chrome moly. Unlike cast components, forging creates a denser, stronger part suited to hard off-road use, high torque, and repeated articulation.
The flange also includes a full-size grease zerk, allowing you to properly grease the center gimbal with a standard grease gun. This improves serviceability and helps the CV last longer than designs with small, restrictive grease buttons.
Proven Before Production
JE Reel tested the 45° CV for more than 11 weeks at 8 hours per day and 3,000 RPM continuous. After testing, the unit was disassembled and inspected, with no wear concerns identified.
The CVs were then installed on Tony Pellegrino’s GenRight build and Mel Wade’s Off-Road Evolution build, with one unit front and rear on each vehicle. Those rigs have accumulated approximately 14,000 to nearly 20,000 miles of trail and hard use before JE Reel approved production.
Key Features
- 45-degree operating angle for extreme-lift and long-travel builds
- Forged chrome-moly construction for superior strength
- Full-size grease zerk for proper CV serviceability
- Designed to help drivers use more suspension travel without limiting the driveline

Upgraded Double Slip Joint for Trophy Trucks & 6100 Race Trucks
JE Reel Drivelines and Tube Works developed an improved double slip joint to solve grease loss, spline wear, galling, and driveline binding in high-travel trophy trucks and 6100 race trucks. The system is available exclusively through JE Reel Drivelines.
The Problem
Standard double slip joints are difficult to grease. Teams often have to force grease along the splines with an extension tube, but suspension movement and shaft rotation push that grease into the hollow driveshaft tube instead of keeping it on the spline surfaces.
Once grease leaves the joint, the Glide Coat wears away. That can lead to spline galling, excessive slop, binding, and in severe cases, components freezing together and damaging an underdrive or pinion.
The JE Reel Solution
This upgraded double slip joint uses 5-axis machined grease ports to provide accessible lubrication to both the front and rear spline barrel sections.
Its patent-pending internal accumulator works like a shock for grease. As the slip joint telescopes in and out, the accumulator pushes grease back into the female barrel instead of allowing it to centrifuge into the driveshaft tube. The result is continuous spline lubrication and improved grease recovery.
Built for Extreme Racing Conditions
Trophy trucks and 6100 trucks run more than 2 feet of rear wheel travel, high horsepower, and extreme torque. When the suspension drops out, the slip joint extends; when the tire hits a bump, it is forced back together.
If the joint binds, that load transfers into the differential and transmission. JE Reel and Tube Works identify this as a contributor to excessive pinion nose-bearing wear and underdrive thrust-bearing wear—especially on trucks with 2–3 inches or more of driveshaft slip.

1310 vs. 1350 U-Joints: The Ultimate Driveline Upgrade Guide
When building a reliable off-road rig, muscle car, or tow vehicle, your driveshaft’s universal joints (U-joints) are the critical links keeping power moving to your wheels. If you are ordering a custom driveline, you will inevitably face a choice: Should you stay with a 1310 series or upgrade to a heavy-duty 1350 series?
Understanding how these sizes differ in strength, dimension, and real-world application is the key to preventing a catastrophic failure on the trail or track.
What Are U-Joints and Why Do They Matter?
Universal joints (U-joints) are flexible, cross-shaped connectors sitting at each end of a driveshaft. They allow the shaft to rotate smoothly and continuously transfer power even as your vehicle’s suspension moves up and down, altering the driveline angle.
Upgrading your U-joint series doesn’t just mean changing the cross itself—it means your yokes, companion flanges, and the driveshaft tubing are all upgraded to larger, significantly thicker components.
What is the Difference Between 1310 and 1350 Series Joints?
The core difference between a 1310 and a 1350 series joint comes down to physical dimensions and ultimate yield strength:
- 1310 Series (“The Half-Ton Standard”): This is the classic factory standard found in most stock Jeeps, half-ton pickup trucks, and classic muscle cars. It uses a cap diameter of 1.062 inches and a body width of 3.219 inches.
- 1350 Series (“The One-Ton Muscle”): Found stock in heavy-duty 1-ton commercial trucks, the 1350 series is built for brutal punishment. It features a larger 1.188-inch cap diameter and a 3.625-inch body width.
1350 U-Joint: Pros and Cons
- Pros: Offers roughly 37.5% more torque handling capacity than a 1310 joint. It delivers unmatched durability, handles extreme shock loads, and provides complete peace of mind.
- Cons: Higher initial cost. Upgrading requires changing out your transfer case and differential yokes. Additionally, because of the larger body size, a standard 1350 joint can have slightly less angular flexibility (operating angle clearance) before binding compared to a 1310.
When Should You Consider Upgrading to 1350 U-Joints?
A 1350 upgrade isn’t always mandatory, but it becomes necessary when your vehicle hits certain performance thresholds:
1. Tire Sizes of 35 Inches or Larger
Large, heavy off-road tires create massive rotational mass. When crawling over rocks or spinning through mud, the leverage exerted by a 35-inch, 37-inch, or 40-inch tire places immense strain on the driveline that can easily snap a stock 1310 joint.
2. High Horsepower and High Torque
If you have swapped in a V8 engine, added a supercharger, or built a high-performance track engine, the severe torque output will rapidly twist or break weaker factory joints.
3. Low-Gear Ratios (Heavy Load)
A common point of confusion is gear ratios. Numerically lower gear ratios (such as 3.21, 3.55, or 3.73) mean your driveshaft spins slower but carries a much higher torque load per rotation to move the vehicle. Conversely, numerically higher ratios (like 4.88, 5.13, or 5.38) multiply torque at the axle, meaning the driveshaft spins faster but with less structural effort. If you are running low numerical highway gears with large tires, your driveshaft is working overtime.
4. Heavy Overland Builds and Towing
Weight kills drivetrain parts. If your rig is loaded down with steel bumpers, winches, rooftop tents, and overland gear—or if you frequently tow heavy trailers—the constant load requires 1350-level strength.
5. Aggressive Driving Styles
If your driving style dictates a “when in doubt, send it” mentality, structural insurance is mandatory. Shock loading—like bouncing on a ledge and landing with the throttle wide open—is the number one cause of broken U-joints.
Front vs. Rear Driveshaft Priorities
Because your vehicle operates in 2WD on the street most of the time, your rear driveshaft is the primary driver and shoulders the bulk of the work.
- The Rear Shaft: Should almost always be upgraded first. If budget allows, a 1350 rear shaft is highly recommended for any modified vehicle.
- The Front Shaft: Can often remain a 1310 or a hybrid joint longer because it only splits the load when 4WD is fully engaged.
Advanced Driveline Factors to Consider
1. The Myth of the Driveline “Fuse” (Trail Repairs vs. Reality)
Many off-roaders deliberately choose a 1310 series joint because they want a cheap, $25 “fuse” that breaks before an expensive transfer case or differential gear set does. While this sounds good in theory, trail reality is very different.
When a 1310 joint fails under heavy throttle, it rarely breaks cleanly. The cross usually grenades, instantly splaying the driveshaft ears or twisting the yoke. Once those component ears are warped, you cannot simply press a new U-joint in on the trail—the entire driveshaft is ruined. Upgrading to a 1350 prevents the failure altogether rather than gambling on a messy trail fix.
2. Generational Axle Upgrades (Why Vehicle Year Matters)
Axle names can be deceiving. For example, a modern factory Dana 44 found in a newer Jeep JK or JL platform is a completely different animal than an old Dana 44 from a Jeep TJ. Modern vehicle platforms feature significantly thicker pinion shafts, stronger differential gears, and larger transfer cases built to withstand massive stress. Because your stock surrounding components are already so robust, they can easily handle the strength of a 1350 upgrade without passing a breaking point down the line.
3. Short Wheelbase Angle Restrictions (2-Door vs. 4-Door)
Your vehicle’s wheelbase length heavily impacts which series can physically clear your suspension lift. Short wheelbase rigs—such as 2-door Jeeps or short-bed classic trucks—experience much steeper driveshaft operating angles when lifted. Because a 1350 U-joint has a physically larger body, it has less internal clearance and will bind at a shallower operating angle than a 1310. If you have a short-wheelbase vehicle with a massive lift, a high-clearance 1310 or a highly specialized high-angle custom shaft may be required to clear the angles without binding.
4. Note for Upgrading Vehicles with Stock Shafts
If you are planning to buy a spare U-joint to keep in your rig for a factory driveshaft, be aware that many modern stock 4x4s do not use standard 1310 or 1350 cross-joints from the factory. Instead, modern platforms frequently use enclosed Rzeppa-style CV joints on the transfer case side. Upgrading to a durable, traditional 1310 or 1350 double-cardan setup requires replacing the entire factory driveshaft and changing out the stock companion flanges for custom output yokes.

What is a Double Cardan Joint? Single vs. Double Cardan Driveshafts Explained
If you are upgrading or replacing the driveshaft in your Jeep, truck, or SUV, navigating driveline terminology can feel overwhelming. One of the most critical decisions you will face is choosing between a conventional single-cardan and a high-performance double-cardan driveshaft.
Understanding how these joints operate—and how they handle operating angles—is the secret to eliminating driveline vibrations and protecting your vehicle’s drivetrain components.
What is a Single-Cardan Driveshaft?
A single-cardan driveshaft (often called a conventional, standard, or non-CV driveshaft) features a single universal joint (U-joint) at each end of the shaft. While highly effective for factory applications at flat, stock ride heights, a single universal joint fluctuates in speed as it rotates through an angle.
When your vehicle’s operating angle becomes too steep—such as after installing a suspension lift kit—these speed fluctuations turn into severe, annoying driveline vibrations that can accelerate wear on your transmission, transfer case, and differential seals.
What is a Double-Cardan Driveshaft? (And How It Works)
A double-cardan joint (commonly referred to as a Constant Velocity or CV joint) consists of two universal joints mounted back-to-back, connected by a specialized centering yoke or ball socket mechanism. Typically installed at the upper end of the driveshaft near the transfer case or transmission output, the two U-joints work in unison.
The magic of the double-cardan design lies in physics: as the shaft rotates, the non-uniform speed fluctuation caused by the first U-joint is precisely canceled out by the second U-joint. This phase cancellation delivers a perfectly smooth, constant velocity of power to the output end, even when handling severe, steep operating angles.
Busting a Common Myth: A frequent misconception is that a double-cardan joint is designed to flex twice as far as a single joint before binding. This is fundamentally incorrect. While some heavy-duty CV assemblies offer slightly higher maximum operating angles, the primary purpose of a double-cardan joint is smooth, vibration-free operation at elevated angles, not extreme articulation clearance.
When Should You Upgrade to a Double-Cardan Driveshaft?
You should consider stepping up to a double-cardan setup in two primary scenarios:
- Replacing a Factory CV Shaft: If your vehicle came equipped with a double-cardan driveshaft from the factory, you should always replace it with a double-cardan setup to maintain proper ride quality.
- Post-Lift Kit Vibrations: If you have lifted your 4×4 or truck and are experiencing a noticeable drivetrain shudder or vibration, your single-cardan layout is likely binding or operating outside of its acceptable angular limits. Upgrading to a double-cardan assembly is the definitive solution to restore a smooth ride.
Technical Requirements for Upgrading
Switching your vehicle from a single-cardan to a double-cardan setup is a highly effective upgrade, but it is rarely a “drop-in” modification. To achieve a perfectly vibration-free setup, keep the following requirements in mind:
- Slip Yoke Eliminator (SYE): If your vehicle utilizes a standard factory slip yoke sticking out of the transfer case (common on Jeeps like the Wrangler TJ or Cherokee XJ), you will need to install a Slip Yoke Eliminator kit to convert the output to a fixed flange or yoke.
- Pinion Angle Correction: For a single-cardan shaft, your transfer case output and differential pinion must be perfectly parallel. However, for a double-cardan shaft, your differential pinion must point directly at the transfer case output shaft (typically $1^\circ$ to $2^\circ$ below the centerline to account for axle wrap under acceleration). You will need adjustable control arms or pinion shims to set this geometry properly.
- Get Accurate Measurements: Because these modifications alter your spacing, never guess on lengths. Always take exact measurements using our step-by-step guide on how to measure a driveshaft before ordering your custom build.

Unlike conventional driveshafts, off-road driveshafts are designed specifically to handle the unique demands of rugged terrain, ensuring optimal vehicle performance. Custom driveshafts are not just an upgrade; they are an essential element that can make or break an off-road adventure. In this article, we will explore the reasons why custom driveshafts are indispensable for those who push their vehicles to the limit in challenging terrains.
Understanding Driveshaft Functionality for Off-Road Vehicles
Off-road vehicles are specifically engineered to navigate challenging terrains, and this design philosophy extends to every component, particularly the driveshaft. Unlike standard vehicles, off-roaders must overcome numerous obstacles, requiring a driveshaft that is just as unique to match their enhanced capabilities. The transmission in off-road vehicles is optimized to effectively transfer torque from the engine to the differential(s) and wheels, which is essential for maintaining momentum during steep climbs and rocky paths. Upgrading to a custom driveshaft can significantly improve power delivery, thereby reducing the risk of drivetrain failure during demanding maneuvers. Additionally, off-road vehicles benefit from increased ground clearance, with aftermarket driveshafts engineered to provide the necessary lift to navigate over obstacles seamlessly. This added clearance keeps the undercarriage safe from damage and enhances the vehicle’s ability to traverse rough terrain.
Challenges Faced by Off-Road Vehicles
Off-road vehicles face unique challenges that standard vehicles rarely encounter. When traversing rugged terrains, these vehicles must deal with obstacles such as rocks, mud, and steep inclines. Each of these situations places extraordinary demands on the driveshaft. The increased torque and forces experienced in rock crawling or off-road trail conditions can lead to immense abuse on the driveshaft components. Conventional, stock driveshafts are typically designed for standard driving conditions and may not withstand the rigors of aggressive off-roading. This vulnerability can result in vibrations, performance issues, or even catastrophic failure, leaving enthusiasts stranded in the wilderness.
Advantages of Custom Driveshafts
When it comes to overcoming the challenges of off-roading, custom driveshafts offer several distinct advantages:
Tailored Design for Specific Needs
Custom driveshafts are engineered to meet the specific requirements of a particular vehicle and its intended use. This customization allows for precise material choices, such as steel for durability or carbon fiber for lightweight performance. High-performance off-road vehicles often require driveshafts that account for increased torque and unexpected stresses, which may not be adequately addressed by off-the-shelf options.Moreover, custom dimensions can be crafted to accommodate unique vehicle setups, including modifications to lift kits, suspension systems, and wheel sizes. This ensures that the driveshaft fits perfectly and operates efficiently within the confines of the vehicle’s system.
Enhanced Strength and Durability
One of the primary benefits of custom driveshafts is their enhanced strength and durability. Made from high-quality materials and engineered to withstand the harshest conditions, custom driveshafts are built to resist bending, breaking, and excessive wear. During off-road excursions, the forces acting on the driveshaft can be immense. A robust custom driveshaft can absorb these forces more effectively than a stock counterpart, significantly lowering the risk of failure. This advantage translates directly into greater peace of mind for drivers who push their vehicles to the limit.
Improved Performance
Custom driveshafts not only enhance the strength of a vehicle’s drivetrain, but they also contribute to overall performance improvements. With precise engineering and superior materials, custom driveshafts facilitate smoother power transfer from the engine to the wheels, reducing vibrations throughout the vehicle.
