Tamiya 51539 RC Big Bore Aeration Damper Pistons - 4pc set, dual 1.6mm holes  [51539]

Upgrade shock response with aeration pistons

The Tamiya 51539 piston set is a simple way to influence how aeration-type big bore dampers behave. Included are four pistons, each drilled with two 1.6mm holes, allowing targeted damping tweaks without major parts changes.

Designed for Tamiya big bore aeration shocks

These pistons fit Tamiya Buggy Big Bore Aeration Dampers (Items 54504/54505). For riders wanting a wider tuning range, you can carefully open additional holes using a pin vise to fine-tune the shock's flow rate.

Practical setup advice

For drivers who race on mixed terrain, swapping piston flow rates is an effective way to balance grip and chassis control. Small piston changes can reduce pitching and improve landings for buggies.
