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

Thin axle spacer for X12, GT and YR10

This thin RC axle shim is listed as Yokomo YOKR12-24SSB, sized 6.4 x 8.5 x 0.127 mm and intended for use with X12, GT and YR10 platforms. The part acts as a fine lateral spacer placed on axles where small increments of clearance or preload are needed.

Typical uses include trimming axle endplay, removing slight lateral movement between hub and bearing seating surfaces, and achieving repeatable wheel offset or gear mesh where tight tolerances are required. At 0.127 mm thickness each shim provides a fine step; several shims can be stacked to reach the exact total thickness without modifying other parts.

Fitting is simple: locate the interface point indicated by your chassis guide or where play is visible, then fit the shim and spin to check for smooth rotation and a secure seat. After adjustment, inspect bearings and spur/pinion engagement to confirm there is no binding. This shim is intended as a setup and tuning accessory, not a primary structural component.
