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. ### ⭐⭐⭐⭐⭐ Muy buen producto *by E***Z on 17 September 2022* Muy satisfecho, calidad, precio y todo en tiempo ### ⭐⭐⭐⭐⭐ It's a legit yukon product *by S***N on 22 March 2025* Originally purchased one of the from a company in Wa state for double the price, this is a wholesaler which cuts the price drastically. Exact same packaging, product (stamped from manufacturer w/ serial numbers and everything), excellent customer service too. If you need a new locker for your gm 10 bolt this is the best option to replace the stock g80 (gov-lock/ gov-bomb). Ran my first one for 150k miles, didn't know fluid replacement was crucial to clutch longevity. I'll be changing this diff gear oil every 30k. True Yukon gear part, exact replacement for almost all gm 10 bolt rearends. Don't believe the -2 at the end of the part #, it's a ydggm8.5-3-30-1 made in the USA. This was less than half price from the local company that produces them, that company wanted to rip me off, this company sold me my parts at a reasonable price. I'll be recommending them to everone. Thank you very much. ## 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.tn/products/386574239-yukon-dura-grip-limited-slip-for-gm-8-5-8](https://www.desertcart.tn/products/386574239-yukon-dura-grip-limited-slip-for-gm-8-5-8) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-22*
