Front Drive Shaft Considerations for Jeep Wrangler JL (No FAD) While Jeep Wrangler JLs equipped with the Front Axle Disconnect (FAD) system can disengage the front driveshaft for improved fuel economy and reduced wear, those without FAD require careful consideration of the front driveshaft setup, especially after lifting the vehicle. Pinion Angle: The Key to Smooth Operation Both the stock Rzeppa-style driveshaft and aftermarket double cardan shafts utilize a single universal joint at the axle end. This shared design element necessitates proper pinion angle adjustment to minimize vibrations, particularly after a lift. Why Pinion Angle Matters: Lifting a Jeep alters...

We don't offer a 1310 series drive shaft for a Jeep JL, only 1350. Or 1410 for people who want/need something even more extreme. This decision was made carefully after fully evaluating the different factors that affect required drive shaft strength. I'll explain the details below but first I want to summarize why each of these different factors matters.  Vehicle weight. The heavier the vehicle the harder it is to push forward, especially uphill.  Horsepower. How much power is available to potentially break things.  Torque. Same as above but different.  Typical tire diameter. The larger the tire diameter the further...

Your Jeep may currently have any one of the four following types of front shafts. Click on the photo that matches yours for more information on that type of shaft and what is available from us.   

The stock Rubicon front drive shaft is a 1330 series CV (double cardan) drive shaft. Unless there has been a failure or damage to a stock drive shaft, there is not usually a need to replace the front drive shaft when lifting this vehicle. For the front CV drive shaft we have two options available. Either drive shaft will be built using upgraded heavy wall tube, larger/stronger slip yoke & spline stub and our “Gold Seal” universal joints.  Go to TJ Rubicon Front Drive Shaft product page.   The S spline is a conventional spline stub that will yield a safe,...

JK Front Drive Shaft We custom build all drive shafts to order and, although we can build some drive shafts by application it is certainly best to take a measurement so the drive shaft is built to fit. The length measurement can be taken with or without the stock drive shaft installed. Measurement is best taken with the vehicle parked on flat ground at normal ride height. Measure from approximately center height (the 3 or 9 0’clock positions) for the best measurement. Need help deciding which drive shaft is right for you? If your drive shaft is not properly sized for...
