Precision Shim Setup for TRF421 Using Tamiya Parts

Hobbyists aiming for consistent handling will appreciate the Tamiya 5x15.2x0.2mm shims tailored for TRF421 chassis. They enable accurate spacing tweaks that help maintain predictable steering and stable drive under load.

What Makes These Tamiya Shims Useful

Made to consistent tolerances, these shims are useful for correcting gear mesh and bearing positions in TRF421 assemblies. The thin 0.2mm profile provides controlled adjustment without upsetting other suspension or transmission settings, and the build quality stands up to frequent running.

Tuning Notes and Benefits

  • Compatibility: Suits TRF421 configurations for straightforward fitting.
  • Precision: 0.2mm thickness for fine, repeatable adjustments.
  • Durability: Robust enough for regular track and practice use.
Correctly set shims reduce side load on gears and bearings, which helps prevent uneven wear and extends component life.
No special tool is needed beyond basic workshop items and a caliper; careful measurement and gentle handling are the keys to a good fit.
Shims alter drivetrain spacing rather than geometry, but small changes can influence traction and response, so adjust incrementally and test on track.
