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

Received at a great discounted price and then when the box came it said USA Standard Gear and not Yukon I then called Yukon and where the support service told me the product was wrongly labeled as listed was an accidentally discontinued Yukon. Revain is wrong again but the kit is still similar to the Yukon with the only difference being that the Yukon has an additional x2 expander and Timkon bearings while the USA Gear has Koyo bearings. In short, this is a kit that is still superb, made for Yukon Dura-Grip holders or Eaton Posi blocks (according to Yukon customer service). However, always check before your aftermarket carrier accepts these bearings or things will not match up properly.
