Spicer Trac-Lok Differential Inner Spider Gear Kit for Dana 35 Rear Axles (27-Spline)

Eliminate hazardous drivetrain backlash, stop invasive rear-end clunking, and restore smooth, quiet power distribution with this genuine Spicer Differential Carrier Inner Gear Kit. Specifically designed to refresh the core internals of your differential case, this factory-matched package is the definitive overhaul solution for vehicles equipped with a Dana 35 (or Dana Super 35) rear axle utilizing a factory Trac-Lok limited-slip carrier.

The internal spider and side gears bear the massive rotational stress of channeling torque directly from your ring gear assembly out to the individual 27-spline rear axle shafts. Over decades of daily driving, heavy towing, or rugged off-road trail use, the gear teeth can suffer from micro-pitting, chipping, or severe surface scoring. When these internal components develop excessive play, they create a noticeable drivetrain "clunk" when shifting between reverse and drive, erratic wheel-spin characteristics over loose terrain, and micro-vibrations that can rapidly accelerate wear on your expensive ring and pinion set.

This original equipment manufacturer (OEM) kit provides a factory-correct internal case rebuild. Every single component in this package is precision-forged from high-grade, heat-treated steel to meet strict original equipment material standards. Choosing a genuine Spicer inner gear kit guarantees exact tooth-mesh geometries and factory-correct surface hardness parameters, ensuring your classic 4x4 handles sudden torque loads without binding or losing structural integrity.
