Tamiya 42165 TRF Blank Damper Pistons Set (4pcs) - Custom Tuning Set  [42165]

Refine Shock Behaviour with Tamiya 42165 TRF Pistons

Model racers seeking fine control over suspension can use the Tamiya 42165 TRF damper pistons to shape oil flow characteristics. The pre-dimpled pistons are ready for careful drilling so you can create exact ports to suit driving conditions.

Which TRF Units Are Supported

These pistons fit a number of TRF dampers, for example the 53901 TRF Special Damper (F103GT) and the 53571 TRF Damper Set (Fluorine Coating). They are intended for use with compatible TRF shock assemblies to extend tuning options.

Practical Tuning Advice

Adopt a measured approach when modifying pistons: start with a small hole, run a few tests, then adjust incrementally. This helps you reach the right balance between control and compliance without causing instability.
