Review on Enhance Performance and Durability with GM Genuine Parts 26064028 Differential Drive Pinion Gear Seal by Jason Arkin

So Revain decided to change something saying it would no longer fit my truck. ACDelco info says it will fit. When I bought it the Revain information was correct. Anyway, this gasket fits the rear diff, drive shaft end, for a 2001 GMC Sierra 1500 5.3L Z71 10 bolt rear diff. Buy RTV with this seal. Some installers only use pressfit lube, but the original gasket had RTV on it when I removed it.
