Tamiya 51539 RC Big Bore Aeration Damper Pistons - 1.6mm x 2 holes, 4pcs  [51539]

Fine-tune suspension with precision aeration pistons

The Tamiya 51539 RC Big Bore Damper Piston Set for aeration-type shocks provides a straightforward upgrade for hobbyists wanting more control over suspension behavior. The kit contains four pistons, each with two 1.6mm ports, letting you dial in damping to match track grip and vehicle balance.

Adjustable ports for tailored damping

These pistons are made to work with Tamiya's Buggy Big Bore Aeration Dampers (Items 54504/54505). For extra tuning range, you can carefully add holes with a pin vise to alter flow and refine shock response.

Practical tips for lap-to-lap consistency

Racers who move between loose, rough, and carpeted surfaces will find these pistons helpful when chasing consistent handling. Changing piston flow allows you to manage body movement and traction for smoother cornering and landing control.
