The JL/ JT Rear Diff Skid (RDS) is a heavy-duty diff skid designed to protect the vulnerable ribs on the JL/ JT rear differential, and provides a smooth surface for you to slide over obstacles.

The new JL Wrangler/ JT axles are a fantastic upgrade over the previous models. However, their shape is not ideal for rock crawling. The thin, exposed lip on the back of the housing is a rock grabber. It also creates a potential risk of cracking a housing or fluid loss if hit hard enough or worn through over time.

As any rock crawling enthusiast will tell you, every inch of ground clearance matters. Anything on your Jeep's underside that can be smooth should be, or it's likely to catch on an obstacle. Next Venture's JL/ JT Rear Diff Skid (RDS) is CAD designed with 3D modeling to retain every bit of possible ground clearance for critical protection you need on the trail. Additionally, you gain clearance to any adjacent skid plates.

Next Venture Motorsports' built the JL/ JT Rear Diff Skid (RDS) from a combination of 1/4" and 3/8" thick steel. This diff skid ties into multiple locations on the differential flange, as well as clamping tight to the snout of the differential. As a result, you will distribute any force -- such as the weight of the vehicle on a rock -- over a much larger area. This skid also extends your coverage to the pinion seal and yoke/flange where the rear driveshaft attaches.

This skid fits both the JL and JT rear M220 Differentials.

*This skid is designed and recommended for use with Next Venture Motorsports' HD JL/ JT Rear Diff Cover * It has been successfully test-fit with TMR, CavFab, Ballistic, Under Cover Fab, and Motobilt Diff Covers by customers. It will *not* work with the Spicer aftermarket covers due to the shape/fin features. Incompatibility has also been found with G2, MetalCloak, Ox Locker, ARB, and Artec/Yukon covers.

Installation with a factory cover is possible, but will require a shim/spacer to account for the factory cover's thinner material. While a stack of washers may do the job, we also offer this laser cut spacer for a clean, 1 piece solution. For ultimate strength, protection, and rigidly tying into all 12 mounting points that the axle offers, we recommend using this product in conjunction with the HD JL/ JT Rear Differential Cover.

FAQs

Do I need to empty my differential fluid before installation?

In our experience, no. The factory gasket in addition to the very thick/ rigid flange on the HD Diff Covers has not leaked any fluid when removing the lower 6 bolts on the cover, as long as the upper 6 bolts are left in place during installation.

This ties into the diff cover; will it cause the gasket to begin leaking fluid if hit hard enough?

In our experience, that would be unusual. When properly torqued with a good gasket, the clamping force of the differential cover bolts along with a very thick/ rigid flange. This prevents most impacts from compromising the integrity of a good gasket/ seal between the cover and differential. The diff skid extends so far forward, it arguably offers more leverage than the diff cover itself. This is why the pinion/ snout clamp components and hardware are so substantial.

What are the torque specs for installation?

18 ft/lbs on the M8 Hardware, and 37 ft/lbs on the 3/8"-16 Hardware
