Fits all Sidewinder & Viper Models
 
The driveshaft saver addresses the loose tolerance between the driveshaft and bearing found in brake caliper assembly. The shafts are spinning in the bearing race and as a result the shaft is wearing away. The driveshaft saver installs inside the hollow drive shaft and expands the shaft to tighten the tolerance. The device can be installed with the shaft still in the sled. Installation does require use of a torque wrench to seat the device.
