Dura Grip Limited Slip Differential

The Yukon Dura Grip Limited Slip Differential (part number YDGC8.25-29-1) is engineered to provide enhanced traction for Chrysler 8.25" axles featuring 29 spline axles and a gear ratio of 2.56 or numerically lower. This positraction differential utilizes composite clutches for smooth yet aggressive engagement, ensuring confidence and performance across various terrains. Constructed with a high-strength nodular case and forged 4320 chromoly spider gears, the Dura Grip is built for ultimate durability and longevity. The unit boasts a fully rebuildable design and is proudly assembled in the USA. Its gears are cut to provide the strongest teeth possible, suitable for demanding off-road conditions. For optimal performance and to ensure long life, Yukon Gear and Axle recommends the use of high-grade, non-synthetic GL-5 gear oil along with their specific LSD (Limited Slip Differential) additive (part number OILADD). The manufacturer explicitly advises against the use of synthetic oil, as it may lead to aggressive or noisy operation. This differential is backed by extensive product testing and state-of-the-art software design, making it a robust choice for vehicles requiring superior performance, durability, and strength.
