Trust Spicer to protect the parts that keep Your fleet on the road. The innovative design of the new Spicer Dura-Tune center bearing assembly maintains the proper driveline angle to maximize driveshaft and component life. This best-in-class center bearing addresses noise, vibration and harshness (NVH) levels to deliver a smoother, quieter operation for downspeed drivetrains. A user-friendly installation further reduces the possibility of future alignment-based issues.
