Spicer Rear Pinion Yoke, Nut & Seal Kit for 1994-2000 Dodge Ram 2500 & 3500 (Dana 80 Axle, 1410 Series)

Eliminate dangerous drivetrain vibrations, fix stubborn rear differential fluid leaks, and restore uncompromised towing strength to your truck with this genuine Spicer Rear Pinion Yoke, Nut & Seal Master Kit. Specifically compiled for 1994–2000 Dodge Ram 2500 and 3500 heavy-duty trucks, this premium original equipment package completely overhauls the primary input connection on high-torque Dana 80 rear axles.

On heavy-duty Dodge Ram platforms—particularly those powered by the legendary 5.9L Cummins Turbo Diesel or the massive 8.0L V10 gas engine—the rear pinion yoke undergoes incredible torsional strain. The input yoke links the driveshaft directly to the differential center section using a rugged 1410 Series universal joint specification (identified by its 1.188-inch u-joint cap diameter and 4.188-inch overall width width). Over high mileage or severe commercial hauling cycles, the yoke's internal splines can develop play, the u-joint bearing cap seats can stretch out-of-round, or the outer sealing hub can become deeply grooved by road grit. A worn or loose pinion yoke causes severe driveshaft slop, dangerous highway vibrations, and quickly destroys the outer rubber pinion seal—allowing expensive gear oil to sling out under the chassis and starve your internal bearings.

This original equipment manufacturer (OEM) restoration package features a premium forged steel input yoke machined to strict factory balance blueprints. Sourcing a genuine Spicer master kit guarantees perfect internal spine engagement, optimal u-joint alignment, and an absolute fluid-tight barrier. Because the massive rear pinion nut is a single-use prevailing torque structural fastener that loses its self-locking properties upon removal, a brand new factory replacement nut is included to ensure maximum clamping force and safely hold your pinion bearing preload configuration.
