R&P Knowledge Hub
A stub end spindle kit is used when an existing spindle is bent, scored, or no longer safe for continued operation. Proper alignment during welding is critical to ensure correct bearing life, brake performance, and tire wear.
This kit uses a standard #84 spindle configuration with L68149 inner and L44649 outer bearings. Confirm bearing numbers and brake flange compatibility before installation.
