Review on 🔧 USA Standard Gear (ZK GM8.6) Complete Overhaul Kit for GM 8.6 Differential by Kirk Womack

I am satisfied with this set and its price. The bearings and races are made by Koyo, the highest quality bearing manufacturer. The carrier bearings came from the USA and the pinion bearings from Japan. The set included screws with a left-hand thread for the sprocket, but I didn't use them (I didn't need them). It came with several gear spacers and a set of multi-layer spacers from the main bearings. It also came with a differential cover gasket, pinch bushing, thread lock, 1-1/4" gear nut, gear seal, gear marking paint, and a brush. It even had a small owner's manual, but that was pretty general information. It included spec information for the Preloaded the gear but from what I found online the specifications given were low that paint thinning with one part paint and three parts gear oil worked very well everything was in the picture plus the gasket it was shipped via Priority mail and I received it three days after ordering This is a high quality kit that is shrink wrapped on a blister box so things don't bump up during shipping.
