2G DSM Girdled Rear Diff Cover

These girdled diff covers are where Frontline Fabrication started. After fabricating hundreds of them out of welded steel, we finally graduated to CNC milling capabilities and these are the result. Today, there are girdled diff covers on most all of the quickest and fastest DSM's in the country with a nearly flawless track record for preventing failures. We're proud to say that these diff covers have gone as fast as 8.12 on Boostin' Performance's Red Demon, with numerous 1.2x 60 foots.

For those that aren't familiar, these diff covers utilize two swivel-foot load bolts that put pretension on the bearing caps to eliminate deflection. This keeps the ring and pinion running true and helps tremendously to prevent failures. On 2G's, you have the added benefit of never having to worry about grenading your flimsy stock diff cover. We mimicked the stock baffling on the inside and added a nice -10AN ORB port for the fill plug for a leak-free seal.

Please note... If product is not listed as in stock, there may be a lead time of up to 8 weeks. Please contact via email with any questions regarding lead times on specific products. As we are a small operation, it is tough to keep everything in stock, and we typically only run a batch of something if there are a few backorders placed. With that being, said, we do try our best to run extras, and intend to stock everything as soon as capacity allows. Thanks for everyone's understanding and patience!
