Product Description

The Yukon Gear & Axle YDGGM14T-3-30-1 DuraGrip limited-slip differential is a high-traction pre-assembled carrier built for GM 10.5" 14-bolt rear axles using 30-spline shafts. Specifically engineered for gear ratios 4.10:1 and lower (including thick-cut gear cases), this dependable unit delivers aggressive traction enhancement while maintaining smooth drivability.

Constructed with forged 4320 chromoly spider gears and Raybestos composite clutch plates in a rugged nodular case, the DuraGrip engages reliably under load, ideal for towing, slippery conditions, or off-road performance. This fully rebuildable design saves time on installation and maintenance. Yukon recommends use of GL-5 gear oil (non-synthetic) with their friction modifier additive for optimal service life. Covered by a standard 1-year warranty, with an upgrade to Yukon's Y.E.S. lifetime protection plan available.
