Yokomo YOKR12-24SSB Axle Shim 6.4 x 8.5 x 0.127 mm for X12/GT/YR10  [YOKR12-24SSB]

Axle shim for X12/GT/YR10

This is an RC-scale axle shim sold under the Yokomo YOKR12-24SSB designation, sized 6.4 × 8.5 × 0.127 mm and intended for use with X12, GT, and YR10 platforms. The part is a thin spacer designed to sit on axles where small increments of lateral clearance or preload are required.

Use cases are tuning axle endplay, eliminating minor lateral movement between hub and bearing surfaces, and achieving consistent mesh or wheel offset where tight tolerances matter. At 0.127 mm thickness each shim offers a fine increment for incremental adjustment; multiple shims can be combined to reach the desired gap without altering other components.

Installation is straightforward: place the shim at the interface point specified by your chassis manual or where you observe play, then test for smooth rotation and secure fit. Inspect surrounding parts such as bearings and spur/pinion engagement after adjustment to confirm there is no binding. This shim is an accessory for model-scale setup and tuning; it is not a structural overhaul part.
