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. Review: Good Quality part for the money. - 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 simple I 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. ## Features - Forged 4320 Steel Internals - Fully Rebuildable; 4-spring, clutch style positraction - Clutch Style Positraction - Assembled in the USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003O755NS | | Best Sellers Rank | #53,767 in Automotive ( See Top 100 in Automotive ) #4 in Automotive Performance Drive Train #574 in Automotive Replacement Drive Train Parts | | Brand | Yukon Gear & Axle | | Brand Name | Yukon Gear & Axle | | Color | Silver | | Customer Reviews | 4.7 out of 5 stars 1,640 Reviews | | Global Trade Identification Number | 00883584260165 | | Grip Size | 8.5" & 8.6" | | Included Components | DuraGrip Limited Slip Differential Positraction GM 8.5" w/30 Spline | | Item Type Name | Dura Grip Limited Slip Positraction Unit | | Item Weight | 0.01 Ounces | | Manufacturer | Yukon Gear and Axle | | Manufacturer Part Number | YDGGM8.5-3-30-1 | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model Number | YDGGM8.5-3-30-1 | | UPC | 883584260165 | | Unit Count | 1.0 Count | | Warranty Description | 1 year warranty against Manufacturer defects | ## Product Details - **Brand:** Yukon Gear & Axle - **Color:** Silver - **Global Trade Identification Number:** 00883584260165 - **Material:** Alloy Steel - **UPC:** 883584260165 ## Images ![Yukon Dura Grip Limited Slip for GM 8.5" & 8.6" Diff, 2.73 & Up Ratio, 30 Spline - Image 1](https://m.media-amazon.com/images/I/61vTkWDo-GL.jpg) ![Yukon Dura Grip Limited Slip for GM 8.5" & 8.6" Diff, 2.73 & Up Ratio, 30 Spline - Image 2](https://m.media-amazon.com/images/I/717Z2ydxd8L.jpg) ## Available Options This product comes in different **Pattern, Style** options. ## Questions & Answers **Q: Will this fit a 86 Chevy C10 with the 8.5 10 bolt rear?** A: no you will need 30 spline axles those trucks used 28 spline axles **Q: This fit a 94 chevy 1500?** A: Yes, this unit will work GREAT in a 1994 Chevy 1500.

My card was saying I had been charged twice, but the gentleman made sure I wasn't and even shipped the card for the warranty next day for 100% free! then called me again to tell me he had the tech people check just to be sure. I cannot say enough good things about this company and the people working there! definitely would buy again if i didn't have the warranty for it! ## 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.vn/products/20830785-yukon-dura-grip-limited-slip-for-gm-8-5-8](https://www.desertcart.vn/products/20830785-yukon-dura-grip-limited-slip-for-gm-8-5-8) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-19*
