Fitment Notes

Fits Dana 80 axles with 35-spline shafts and 4.10 & numerically higher gear ratios only - not compatible with 3.73 and below (see YDGD80-3-35 for lower ratios)
Verify axle spline count before ordering - some Dana 80 applications use 37-spline shafts and require a different carrier
Confirm differential type in your specific vehicle - factory options vary; not all listed vehicles were equipped with a Dana 80
ABS compatible
Requires two bottles of Yukon LSD additive (part number OILADD) for proper clutch operation
Non-synthetic GL-5 gear oil strongly recommended - synthetic oil may cause noisy or aggressive engagement

Features

Clutch-type limited slip design provides smooth, progressive traction engagement suitable for street, towing, and light off-road use
4-pinion configuration for optimized torque distribution and maximum power delivery to both rear wheels
Forged 4320 chromoly steel spider gears deliver high-strength durability under heavy load and high-torque conditions
High-strength nodular iron carrier case resists flex and wear in demanding 1-ton truck applications
Raybestos composite clutch pack engineered for long service life and consistent engagement
4-spring preload design tuned for smooth street-friendly operation without sacrificing traction
ABS compatible - no modification required for ABS-equipped vehicles
Fully rebuildable - clutches and internals are serviceable, extending the unit's usable lifespan

Product Description

The Yukon Gear & Axle YDGD80-4-35 Dura Grip is a clutch-type limited slip differential engineered for the Dana Spicer 80 rear axle with 35-spline shafts and gear ratios of 4.10 and above. Built to handle the torque demands of 3/4-ton and 1-ton trucks from Ford, Dodge, GMC, and Chevrolet, this unit replaces the factory open or worn LSD carrier with a positraction unit that delivers power to both rear wheels - improving traction under load, on loose terrain, and during hard acceleration.

Constructed with a high-strength nodular iron case and forged 4320 chromoly spider gears, the Dura Grip is built for the heavy-duty demands of trucks that tow, haul, and work hard. The Raybestos composite clutch pack provides consistent, controlled engagement without the harshness of a locker, while the 4-spring preload design keeps operation smooth for everyday driving. The unit is ABS compatible and fully rebuildable, making it a long-term solution over non-serviceable alternatives.

This carrier is designed specifically for the 4.10-and-up carrier position in the Dana 80. Verify your axle's spline count (35 vs. 37) and gear ratio before ordering to ensure correct fitment - not all Dana 80-equipped vehicles use the same carrier or spline configuration. Use only high-grade non-synthetic GL-5 gear oil with two bottles of Yukon LSD additive (OILADD) to ensure proper clutch function and long-term performance.
