RTS premium solid pinion spacers are designed to retain your pinion depth and settings for greater strength and stability. These spacers can be reused if you need to take apart and reassemble the carrier.
Replace that failure prone crush sleeve with a solid spacer.
Fits Standard 28 spline small pinion, stock or Daytona style support.
Comes with a shim pack so you do not have to machine the spacer to fit.
Simply add shims for less preload or remove shims for more preload.
