Yokomo S4-S202-25 2.5mm Pistons for 13mm Shocks Upgrade  [S4-S202-25]

Improve Shock Control with Yokomo S4-S202-25

The Yokomo S4-S202-25 is a set of 2.5mm thick pistons made for 13mm shocks, built to sharpen damping feedback and tuning accuracy. These pistons help refine shock behaviour and are compatible with the SOR-030 and MOR-020 chassis, making them a straightforward upgrade for hobbyists aiming to improve handling and consistency.

Precision Design and Damping Options

The S4-S202-25 pistons use a 2.0mm x 2-hole layout to offer incremental control over oil flow and compression. That layout supports fine-tuning of rebound and compression characteristics so you can dial in traction across a range of surfaces. Manufactured for durability, these pistons hold up under frequent track use.

Fitment and Use Cases

Specifically suited to Yokomo SOR-030 and MOR-020 chassis, these pistons work well for racers and club drivers who want more consistent shock response. They are a practical replacement for worn pistons or a targeted performance tweak for setups that need crisper damping control.
