The bearings and races were Koyo, a top quality bearing manufacturer. The carrier bearings were USA and the pinion bearings were Japan. The kit came with left hand threaded ring gear bolts, though I didn't use (need) them. It came with several pinion shims and a set of sandwich shims from the carrier bearings. It also came with a differential cover gasket, crush sleeve, thread locker, 1-1/4" pinion nut, a pinion seal, gear marking paint and a brush. It even had a little instruction booklet, but it was pretty general information. It had information about pinion pre-load specs, but from what I found on the internet, the specs provided were on the low side. So check the FSM for what GM has to say on the issue, if you can find one. I found that diluting the paint with one part paint and three parts gear oil worked very well. It was every thing in the picture, plus the gasket. Shipping was priority mail and I had it in three days of ordering. Its a nice, quality kit packaged on a shrink wrap type of blister board so that things don't bang against each other in shipping. ### ⭐⭐⭐⭐⭐ Differential replacement bearings *by on Reviewed in the United States February 24, 2026* Great quality ### ⭐⭐⭐⭐⭐ Worked out perfect! *by on Reviewed in the United States July 20, 2024* Just what I needed to put my rear axle back together. Worked great everything fits perfectly. The kit included everything that you needed for the replacement of the rear gears on the axle right down to the marking grease. ## Frequently Bought Together - USA Standard Gear (ZK GM8.6) Master Overhaul Kit for GM 8.6 Differential - Yukon Gear & Axle Dura Grip Limited Slip Differential Positraction, 30 Spline, 2.73-Up, Compatible with 8.5"/8.6" GM Axle, YDGGM8.5-3-30-1 - USA Standard Gear (ZG GM8.5-373) Ring & Pinion Gear Set for GM 8.5 Differential --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/10685869-usa-standard-gear-differential-master-overhaul-rebuild-kit-for-1999](https://www.desertcart.tn/products/10685869-usa-standard-gear-differential-master-overhaul-rebuild-kit-for-1999) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-25*
