Refine Shock Feel with Tamiya 53977 - TRF501X

For model racers focused on handling, the Tamiya 53977 - TRF501X Low Friction Piston Set offers a practical way to tailor shock response. Manufactured from polyacetal (POM), the pistons present multiple hole diameters so you can adjust oil flow and tune damping characteristics precisely.

Adjustable Piston Options for Tuners

The variety of hole sizes gives you greater control over compression and rebound behaviour, letting you adapt to different surfaces and driving styles. Note that these pistons are not designed for CVA or TRF dampers, so ensure compatibility with your shock bodies before purchase.

You can mix sizes for testing, but confirm the piston bore and shock shaft fitment to avoid binding or leaks.
Polyacetal is selected for its wear resistance and low friction; under normal use it maintains consistent performance over many runs.
Begin by comparing two piston sizes with the same shock oil, then adjust oil viscosity or spring rate to fine-tune handling without confounding variables.
