Specialist Tamiya 51539 Big Bore Aeration Damper Pistons - 4 pieces, 1.6mm x 2  [51539]

Precision aeration pistons for better shock control

The Tamiya 51539 RC Big Bore Damper Piston Set is aimed at hobby drivers who want more precise shock behavior. The set includes four pistons, each with two 1.6mm openings, offering clear steps for damping adjustment to suit different track conditions.

Compatibility and simple modification

These pistons are compatible with Tamiya Buggy Big Bore Aeration Dampers (Items 54504/54505). If you need additional tuning range, carefully drilling extra holes with a pin vise will let you change flow characteristics incrementally.

When to change piston flow

If you swap between hard-packed and loose surfaces often, changing piston porting can help maintain predictable handling. Adjusting the pistons tunes shock absorption and helps reduce unexpected chassis roll or dive.
