BBK Performance

Polyurethane Axle Bump Stop Rear by BBK Performance®. These polyurethane rear axle pinion snubber bushings are recommended with our Gripp lowering spring kits as they deliver the proper height for the new lowered stance.



  • Prevents excessive rear axle housing torque
  • Ideal size for use with BBK lowering spring kits
  • Made of durable polyurethane
  • Comes with installation instructions
  • Limited 1-year warranty
  • Proudly made in the USA

Under hard acceleration, the rear axle in your car torques upward at the pinion yoke. If not restrained by the pinion snubber bushing, located on the underside of the vehicle over the differential, this could cause severe driveshaft and U-joint problems. Lowering a vehicle changes the distance between the snubber and the differential housing, requiring replacement with this polyurethane version. Polyurethane is firmer and more resistant to chemicals and the elements, so this snubber bushing will also outperform and outlast the stock rubber bushing.

The Polyurethane Rear Axle Snubber Bushing comes with detailed instructions to guide you through the installation. It's backed by a 1-year limited warranty against defects in materials or workmanship, as long as the product was installed according to BBK guidelines.
