Only unforeseen mod I had to do was grind the end of my axles down slightly. Couldn’t slide the main pin through the carrier after I installed this one instead the stock carrier. Stock carrier had taken a crap after previous owner had not put oil in in. Spider gears gone, clutches worn. Had to take off maybe 2mm on each of them. The. The pin could slide through. I’ve been running this one for about two months now. It does click and pop some when turning sharp in parking lots, stuff like that. But I don’t hear anything out of it when driving. Seems to hook up well, my truck drives the winter roads like a tank. Looking forward to some off roading. I’ll let you know if it doesn’t hold up. Review: Perfect for the Chrysler 8.25 - I like it. I won't tell you how easy it was to install because it wasn't. I'm not going to give you a false sense of hope that this just slaps in. If you don't know how to regear then take it to a pro that does. With that said... I like it. I don't feel it engaging and disengaging. On my tru-trac when it's free spooling it feels almost like I'm driving on cobble stone road. This lsd is super quiet and so far has been working great. I'm on 35in boggers. I plan on abusing this lsd. We will see how it holds up. ## Features - ✅ Fits GM 8.5" 10-Bolt Differentials – Designed for vehicles with 28-spline axles and 2.73+ gear ratios for optimal performance. - ✅ Smooth Limited-Slip Performance – Provides traction when needed while allowing smooth turns, ideal for daily driving & off-road use. - ✅ Durable Clutch-Style Design – Heavy-duty friction plates ensure superior power transfer without excessive wear. - ✅ Drop-In Installation – No Special Tools Required – Direct replacement for factory open differentials; uses LM102949 bearing & LM102911 race. - ✅ OEM & Aftermarket Compatibility – Replaces Eaton 187C149A, Auburn Gear 542018, Yukon YD GGM8.5-3-28-1 & more. 2-Year/100,000-Mile Warranty. ## Images ![PowerTrax LS201028 Limited Slip Differential Carrier For GM 8.5", 2.73 Ratio & Up, 10-Bolt, 28 Spline - Fits Chevy, GMC, Buick, Pontiac, Oldsmobile, Cadillac – Replaces Eaton 187C149A, Auburn 542018 - Image 1](https://m.media-amazon.com/images/I/61UHACYcVaS.jpg) ![PowerTrax LS201028 Limited Slip Differential Carrier For GM 8.5", 2.73 Ratio & Up, 10-Bolt, 28 Spline - Fits Chevy, GMC, Buick, Pontiac, Oldsmobile, Cadillac – Replaces Eaton 187C149A, Auburn 542018 - Image 2](https://m.media-amazon.com/images/I/615TzmQMtKL.jpg) ![PowerTrax LS201028 Limited Slip Differential Carrier For GM 8.5", 2.73 Ratio & Up, 10-Bolt, 28 Spline - Fits Chevy, GMC, Buick, Pontiac, Oldsmobile, Cadillac – Replaces Eaton 187C149A, Auburn 542018 - Image 3](https://m.media-amazon.com/images/I/61qW1M8WHCL.jpg) ![PowerTrax LS201028 Limited Slip Differential Carrier For GM 8.5", 2.73 Ratio & Up, 10-Bolt, 28 Spline - Fits Chevy, GMC, Buick, Pontiac, Oldsmobile, Cadillac – Replaces Eaton 187C149A, Auburn 542018 - Image 4](https://m.media-amazon.com/images/I/71+tywHdRAL.jpg) ![PowerTrax LS201028 Limited Slip Differential Carrier For GM 8.5", 2.73 Ratio & Up, 10-Bolt, 28 Spline - Fits Chevy, GMC, Buick, Pontiac, Oldsmobile, Cadillac – Replaces Eaton 187C149A, Auburn 542018 - Image 5](https://m.media-amazon.com/images/I/712E2nLFvAL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Yupyupyup *by D***A on February 9, 2020* Work well for my 99 Dakota 4x4.

Was pretty difficult to get onto the ring and also be very cautious when getting higher gears with this. I put this on with 4.56s and the pin for the center would not come out because of the gear being in the way. I had to shave a slot to make it squeeze past. Nothing that can’t be fixed but not a perfect fit. Other than that, both my tires are spinning and installation was a success --- ## 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.hr/products/50069297-powertrax-ls201028-limited-slip-differential-carrier-for-gm-8-5](https://www.desertcart.hr/products/50069297-powertrax-ls201028-limited-slip-differential-carrier-for-gm-8-5) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-07*
