Tamiya 51539 Aeration Damper Piston Set for Big Bore Shocks - 4pcs, 1.6mm x 2  [51539]

Control aeration flow for smoother handling

The Tamiya 51539 RC Big Bore Damper Piston Set gives hobbyists a reliable option to alter shock behavior on aeration-type dampers. The pack contains four pistons, each with two 1.6mm apertures, enabling clear tuning steps to suit your vehicle and track.

Compatible with Tamiya big bore aeration units

These pistons are suitable for Tamiya Buggy Big Bore Aeration Dampers (Items 54504/54505). If you need finer control, you can carefully drill additional holes with a pin vise to change the damper response.

Why porting matters on mixed surfaces

Switching piston porting can help with transitions between loose dirt, hardpack and carpet tracks by adjusting how the shock absorbs impacts. Proper piston selection supports predictable steering and reduced chassis upset.
