This is a new polished aluminum differential rear cover for GM 10 bolt rear ends. Made from heavy duty cast aluminum with ribbed design and thick gasket flange for added strength. Includes bolts.
Fits many newer vehicles with 8.5" ring gear. We do not have a complete application list so recommend checking your particular application to be sure. Will usually not fit front truck differentials due to clearance issues with steering center link shaft.

FIT:I have a 2wd V6 2004 Silverado with the 10 bolt rear end. The finned aluminum cover fits it great on the rear.Gasket:You will need to buy a gasket.Bolts:This cover comes with nice SAE 5/16" bolts. They did not fit my 2004 model and the shop had to provide new 8mm metric bolts. Older vehicles use the 5/16" SAE bolts. New ones apparently use metric 8mm. I'm not sure what length was required, the cover is pretty thick. Because of the thickness of this new cover, the OE bolts are probably too short. I'd order this set of 14 ( 4 extra ) 30mm long, 8mm bolts from Amazon:https://www.amazon.com/Trans-Dapt-Performance-9283-Differential-Aluminum/dp/B01IDGFBTW/ref=sr_1_fkmrnull_1?keywords=trans+dapt+9283&qid=1555110631&s=automotive&sr=1-1-fkmrnull.Drain plug:The included drain plug is not magnetic. I like to use a premium magnetic plug. I bought two 1/2" NPT plugs. One for the drain in the cover and one for the OE fill port in the housing. See photos. Get one that takes an allen wrench or 3/8 drive to preserve ground clearance.Clean Up:The cover had some sharp edges. I took a small file and knocked the sharp edges off the 90 degree corners of the gasket surface.Also, the bolt holes had sharp edges. I used a grinding stone, see photo, to clean up and chamfer the bolt holes on the gasket side.The drain hole had a little flashing on the I.D. on the inside. I was afraid these edges would catch and hold junk. I used the small grinding stone to clean the I.D. of the drain hole on the inside of the cover - the outside of the drain hole was clean and I didn't want to hurt those threads. After the filing and grinding, I washed the cover to remove the filings and debris from the stone.This is a great cover at a great price. It need just a little attention prior to installation. All on the work I did took less than 10 minutes. Just make sure you have bolts on hand that fit your axle

Used this (chrome stamped steel version) to replace the 10 bolt 8.5" rear diff cover on my 97 Silverado. Fit was good, quality seems good. No leaks yet. I used a Fel-Pro RDS55028-1 gasket and RTV on the drain plug.

Fit perfectly with my Felpro gasket. Had to modify the brackets for brake lines as this cover has a thicker edge than the stock cover. Looks great!

Looks great, fit great, and went on with ease. Used my trusty Felpro gasket and Iām back on the road after changing my seals and bearings and flushing out the differential.

Contrary to what the description says this cover does not fit any Camaro or Firebird Camaros and Firebirds come with a 7.5 ring gear rear end
