Yokomo S4-S813A Aluminum Shock Caps - SO2.0/MO2.0 Upgrade  [S4-S813A]

Yokomo S4-S813A Precision Shock Caps

Built for tuners who want dependable damping and longer service intervals, the Yokomo S4-S813A aluminum shock caps fit the SO2.0 and MO2.0 chassis and help refine shock response. They are aimed at improving shock absorption and overall ride stability without drastic setup changes.

Durable Aluminum Build

The Yokomo S4-S813A caps are machined from quality aluminum for a stiffer, more resilient top end compared with stock plastic caps. They seat cleanly on SO2.0 and MO2.0 shocks and allow finer damping adjustment so your car holds its line across varied surfaces.

Simple Installation and Reliable Sealing

These caps include a service-friendly drain screw to make bleeding and maintenance easier. Their improved seal reduces fluid loss, keeping damping consistent during long practice runs, club races, or casual bashing.
