Tamiya 53978 - TRF501X Low Drag Piston Upgrade  [53978]

Improve Damping Response with Tamiya 53978 - TRF501X

The Tamiya 53978 TRF501X Low Friction Piston Set gives racers and club drivers a simple way to refine suspension behaviour. Made from polyacetal, these pistons lower friction inside the shock body and allow for more repeatable adjustments. They are intended for use with TRF501X chassis layouts to help dial in handling for different track surfaces.

Why Use Polyacetal Pistons?

Polyacetal offers a smooth bearing surface and good dimensional stability, which reduces unwanted drag during shock travel. That lower friction helps cleaners steering inputs and makes small tuning changes more effective.

Compatibility Guidance

Designed specifically for TRF501X dampers, these pistons do not work with CVA or TRF damper types. Ensure your shock parts match the intended design and take care during assembly to avoid damaging seals.
