GMC Sierra Pinion Washer

The GMC Sierra Pinion Washer helps keep the differential assembly locked to ensure power is always translated into movement without any involuntary gear drift. The small steel spacer sits behind the pinion flange where it helps distribute clamping force, absorb vibration, and shield lubricant seals. These functions and attributes have made the Pinion Washer known for its reliability among GMC truck owners. Suitable for the early 1500 workhorse to Denali luxury trim for every factory model GMC pickup, this component fits several Sierra model years and drivetrain packages. Whether housing a traditional two-wheel-drive axle or a heavy-duty four-wheel-drive GMC differential, the Pinion Washer helps maintain gear preload so that heat remains low and efficiency remains high. The Pinion Washer in the cupped spring style was introduced by later generations. These have a slight flexing ability to maintain a degree of torque as parts settle over high mileage. The earlier flat versions, although not the same, were still capable of providing a reliable and good surface area for the nut to grip. Due to its ability to protect the ring and pinion from misalignment, the unit improves steering consistency and braking predictability. Both are critical safety attributes sought after by GMC drivers who haul payloads, tow boats, or drive the city streets in their Sierra. During seal service, the replacement of the Pinion Washer that has gone into fatigue helps prevent oil leaks from damaging expensive gears and bearings. Also, doing so improves the service life of every Sierra drivetrain. The low profile design is appreciated by owners as it preserves rotating mass. Furthermore, the slight cup angle on late Pinion Washer versions compensates for micro movement. With this, the assembly remains quiet even when a Sierra is on the greatly rough of trails. Striking the right balance between mechanical toughness and smart features that self-adjust, the Pinion Washer provides one more reason for GMC enthusiasts to confidently use their Sierra for work, play, and everything in between.

Each OEM GMC Sierra Pinion Washer we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
