Enhance Performance with Proform 66668 Black Aluminum Differential Cover: Perfect Launch Logo & Bearing Cap Stabilizer Bolts for GM Review

Found the best price for a few euros here. Perfect for my Nova pads and everything I count. Will buy for other rear wheels in the future

I almost bought this item after reading the reviews. All complaints have been resolved. The longer bolts included in the kit come with washers that won't scratch or chip the paintwork. Everything about this cover was great. To be honest, I've decided to share this information.

I fitted this to my Chevelle 72 with an 8.2 10 bolt differential and so far no problems. This thing is heavy duty and allows me to run the car at high rpm without damaging the bearing mounts. I highly recommend welding axle tubes and adding upgraded axles with 1/2" studs if using slicks on the track!

Excellent design, price and quality, except for the color. I barely scratched the paint with my nut when I tightened one of the screws and the paint chipped. I took the lid off, sealed the "Perfect Launch" embossing with tape, sandblasted, painted POR 15 and reinstalled. Looks great! Still worth the price and I would buy it again. The manufacturer only has to fix the paintwork problem so you don't have to fix it yourself. I also torqued ten cap screws to 25 lbs with blue Loctite, two bearing…

Perfectly matches my 96 K1500 Z71 case. This will work for your GM rear with ten bolts. I bought this because my filler plug was cracked by the previous owner and the diff cap was pretty rusty. Fits the bill perfectly! Bearing cap stabilizer bolts probably don't make much sense to me since I don't use crazy force, but fill and drain bolts are fine. Just make sure you measure the fluid going into the diff since the filler plug is higher up. My differential takes 2.2 liters. You can also find out

Really wanted to give it a full five but the screws that come with the cover are pretty crappy. End cap, you expect a set of ARP screws to go in there. Other than that it looks good, well sealed (DO NOT use a gasket. Ultra Black or Hi-Temp RTV is what you want; and remember to use the FACTORY fill hole as a guide. Open it up, use that Rear cover fill hole for adding fluid, and if it starts dripping out of the factory fill hole, stop, it's full.), and the stock mounts are pretty steep. It's just

The axle cover is very thick and very well made. It had a few holes on the glue from the pour, I had to use a high temp RTV to prep the surface before installing. The equipment provided COEXISTS!. Due to the extra thickness of the cover, the included screws weren't long enough, I had to go and buy new hardware (longer grade 8 screws) to compensate for the extra thickness. Never use the supplied stainless steel/rubber washers. They don't crush properly after up to 25 ft-lbs of torque. I had to…
