Description

JL Rear Diff Skid (RDS) for M220

The JL Rear Diff Skid (RDS) is a heavy duty skid designed to protect the vulnerable ribs on the JL rear differential and provides a smooth surface for you to slide over obstacles. All components are CNC laser cut and formed by a CNC press brake for a precise fit. We proudly fabricate and hand-weld this product in the USA.

The new JL Wrangler 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. Our JL 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.

If you find yourself watching the Lite Brite YouTube channel, and come across their 2019 King of the Hammer’s videos… this is one of the many pieces of metal you will hear banging against — scratch that, breaking — some of the rocks in Johnson Valley underneath their JL.

Product Details

We build the JL 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.

In contrast to our similar JT Rear Diff Skid, this skid is built specifically for the JL. We offer almost identical, but slightly different products due to small differences in the axle housings.

*This skid is designed and recommended for use with our HD JL Rear Diff Cover * It has been successfully test fit with TMR and Motobilt Rear Diff Covers by customers. It will *not* work with the Spicer aftermarket covers due to the shape/fin features.

Installation with a factory cover is possible but requires a shim/spacer to account for the factory cover’s thinner material. For ultimate strength and protection, we recommend using this product in conjunction with our HD Cover.

Included with purchase:

(1) Rear Differential Skid Plate with Top Clamp
(2) Hardware Sticks with hardware/bolts
(12) 12 Point Flange Bolts Class 10.9 Chromed (enough for matching hardware all the way around the rear diff 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 our 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. Our 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.

Our Standard Semi-Gloss Black Wrinkle Powder coat option adds 2-3 days to lead time prior to shipping. Other colors may add a lead time of 5-10+ days. Please call for a more accurate lead time.

    Got only 1 set of new bolts with my order of front and rear covers and skid.
    Your supplied bolts seems a little short for use though skid and cover. I bought 6 new ones 5mm longer. Not. Big fan of rivnuts. Would like to see rivnut plates go away and just use weld nuts directly on the skid.
