🔧 Proform 66667 GM Black Aluminum Differential Cover | Perfect Launch Logo + Stabilizer Bolts & Bearing Cap Review

Really nice cover. Comes with all hardware and is thick, not thin like the original. The only thing I didn't like is that the black finish scratches easily.

This cover is excellent, it serves a great purpose to tension the retainer covers so they don't break which is a common problem when fitting a locker. This releases this very strong cover and helps prevent breakage

Runs and works great but when I tightened the bolts the paint around the bolts peeled off about a quarter of the way around each bolt. But it's only cosmetic. Also, the bolts weren't long enough to use the factory brake cable brackets.

Bought as a replacement for my V8 S10 Factory 7.5" 10 bolt rear triangle. The diff cover is pretty massive, the main bearing support bolts provide plenty of support for the tiny factory bolts at 10, should up be fine up to 400hp Let's see if it can take my violence!

I needed a new diff cover with a fill and drain plug because the fill plug in the diff had frozen in place and the head had come off . I ordered it from Revain and when I put it on everything looked fine. I screwed everything with screws, filled the rear with 75W90 oil for $ 60 and a special liquid for pos. And after a few minutes I started to see the leak through the casting and not near the bolt holes. I have uploaded a video to my YouTube channel showing the poor casting quality and where…

I bought this because I needed a drain plug on the rear differential of my 4WD Astro. As a bonus I find the additional support of the differential bearing caps and the hot look. It's an easy replacement if you're not afraid of oil, and it's probably time to add some good synthetic gear lube to your diff. The filler plug is not a level plug, you should still use a factory filler plug. The only caveat is unscrewing the drain plug, putting part of the gear on the threads and putting it back in. I…

This thing is designed to hold/support bearing caps and is sized to fit THIS SPECIFIC VEHICLE! (1996 GM F body) However, it does not completely cover the bearing caps when installed, but only covers about half of the outer edge, which is far from ideal! If the screws in this cover's "support system" were a little closer together (moved inward), it would be MUCH more efficient for its intended purpose. Anyway it's better than nothing but certainly not an exact match and terrible value for money.
