Works great. Installed in my truck for towing and in-the-woods hauling capabilities, replacing a stock open carrier. No issues, and I have put about 200 miles on it since the install (don't drive that truck much). No abnormal noises. ### ⭐⭐⭐⭐⭐ Better than factory well made *by on Reviewed in the United States February 21, 2026* I use this unit on a 1968 Camaro 12 bolt rear end. It came complete well-made machine surfaces everything fit as designed. I used the factory Yukon additive. I have 6000 miles under the rear end with a 327 manual transmission and both tires spin when power applied no slippage. Going forward I would not look for a used GM unit and just use a Yukon much simpler. It is well built and works well. I did buy the wrong unit because they have three models for different gearing and it was an easy exchange. Great customer service. ### ⭐⭐⭐⭐⭐ Good Quality part for the money. *by on Reviewed in the United States August 16, 2025* Replaced the open differential unit in my 99 Dodge Durango with this limited slip unit and it is an awesome upgrade!On the 9.25 Dodge differential replacement is simpleI suggest using only "Timkin" bearings, good quality gear oil and limited slip additive. I used Lucas 85W 140 gear oil and their additive. The differential is working perfectly. While you have things apart it is a good time to inspect/replace the outer axle bearings and axle seals which are very easy to replace at that time as well. ## Frequently Bought Together - 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 - Friction Modifier Positraction Additive for Limited Slip Differentials - Yukon Gear & Axle (CK GM8.6) Carrier Installation Kit for GM 8.6 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.sn/products/20830785-yukon-dura-grip-limited-slip-for-gm-8-5-8](https://www.desertcart.sn/products/20830785-yukon-dura-grip-limited-slip-for-gm-8-5-8) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-09*
