Product Description

The Yukon Gear & Axle YDGD44-4-30-1 Dura Grip limited-slip differential is engineered for Dana 44 axle housings equipped with 30-spline axle shafts and 10-bolt covers. Designed to work with gear ratios of 3.92:1 and upward, it delivers dependable, aggressive traction while maintaining smooth vehicle behavior thanks to its four-spring composite clutch system built into a rugged nodular iron case.

Inside, the unit leverages forged 4320 chromoly spider gears and precision-machined clutch components for long-lasting reliability and reduced heat buildup. The double-drilled design accepts both 7/16" and ½" ring-gear bolts, with YSPBLT-027 adapter support for 3/8" bolt patterns. Yukon recommends using high-grade GL-5 non-synthetic gear oil paired with their LSD additive to ensure optimal slip behavior - synthetic oil may induce noise or harsh engagement.

Backed by Yukon's one-year limited warranty (with optional lifetime Y.E.S. coverage), the YDGD44-4-30-1 is ideal for restoring performance in classic trucks, Jeeps, or SUVs with Dana 44 axles - or upgrading existing gear systems needing improved traction without replacing the housing. Fully rebuildable and assembled in the USA, it delivers excellent durability for towing, off-road use, or daily driving in a variety of gear ratio configurations.
