      Pinion flange

      Exactly what I needed. I wasn’t sure it would be the right fit for my build but once I got it and installed it I knew it was perfect. It’s well made

      Easier than gasket maker

      Serviced my differential and used this instead of a gasket maker sealant, super easy no leaks, would recommend.

      Great kit every thing you need in one kit

      This kit is worth it, if nothing else, just for the shims. They are very cleverly designed - there are two sets of thicker shins that overlap each others’s inner diameter. Then there are plenty of very thin .006” shims that you can put between the big shims.

      better than new

      rebuilt my 140,000 mile rear axle , , used this sleeve to save the money from buying a new one , easy install , just center the repair sleeve as centered on the flange ,, put the included drive cup over the repair sleeve, and hammer it on till it bottoms out,, remove the drive cup and discard ,, and that's it,, easy peasy

      Crush slieve eliminators

      This is the way to go to set backlash. Very simple to use. And beats the heck out of crushing that crush slieve type.

      Only way to go

      Worked perfectly. Only way to go in terms of crush sleeve or not. After having to replace my pinion bearing after not crushing the sleeve enough the first time. These are the thing I'll use.

      Works great

      I’ve had this gasket on for a while now and it’s worked great. I bolted on the ford performance rear differential with this gasket and it’s given me zero issues
