Take Control Of Your Traction Without Giving Up Comfort

If you’re looking for a serious traction upgrade that won’t beat you up on the road, the Yukon Dura Grip is the perfect middle ground. This clutch-style limited slip differential delivers consistent grip when you need it, while still allowing smooth cornering and quiet street manners when you don’t. It’s built for drivers who tow, haul, and occasionally head off-road, but still want a comfortable and predictable ride day to day. Whether you’re backing a trailer into a tight spot or climbing a loose hill with a load in the bed, the Dura Grip keeps power going to both wheels to get the job done. Unlike aggressive lockers, it engages with a more refined feel that works great on daily-driven trucks. This unit is also fully rebuildable, so you don’t have to worry about replacing the whole thing down the line. With performance you can feel and durability you can count on, it’s a smart upgrade for any hard-working truck.

Built For Strength Tuned For Everyday Driveability

The Yukon YDGGM11.5-30-1 Dura Grip is engineered for 11.5-inch axles with 30-spline shafts found in GM 2500HD and 3500HD trucks from 2001 to 2025, and Dodge Ram 2500 and 3500 models from 2003 to 2019. It uses a proven clutch-style postreaction design that balances traction and street-friendly behavior, offering smooth engagement without the noise or harshness of a full locker. Inside, it features forged 4320 steel gears that are precision cut to maximize strength under load, making it suitable for heavy towing and moderate off-road use. The carrier is fully rebuildable, making future service or tuning possible without replacing the entire unit. Yukon recommends high-grade GL-5 gear oil along with their limited slip additive for optimal performance and quieter operation. Synthetic oil is also compatible, but may result in a slightly more aggressive feel. Assembled in the USA and backed by a 1-year warranty, the Dura Grip is a reliable upgrade for anyone looking to improve traction without sacrificing comfort or control.
