Hobbyists upgrading classic XB kits will find the XRAY 352076 - XB808 Aluminum Bearing Collar Set useful for 13x20 differential bearings. These collars keep bearings seated squarely in the front and rear diff bulkheads for reliable alignment.
The collars are designed to prevent bearing drift and to work with the capturing screws to spread impact and running loads. That controlled spacing reduces uneven wear and helps bearings last longer between services.
This two-piece set matches the original XB808 bulkhead layout, making it a straightforward replacement or upgrade for owners maintaining older cars. It is aimed at those who value stable bearing retention on track or during weekend runs.
