3RACING 13mm Aluminium Shock Spring Base Cover for Damper - 3RAC-DP01/PK Racing Tune  [3RAC-DP01/PK]

Track focused spring seat for 3RACING 3RAC-DP01/PK

The 3RACING 13mm Aluminium Shock Spring Base Cover is designed with racing setups in mind, delivering a stable interface between spring and shock top to reduce variables in damper behaviour. It helps drivers achieve more consistent compression and rebound response lap after lap.

Performance fit and function

Using a lightweight aluminium design, the cover resists deformation under repeated load and improves spring retention compared with softer materials. This yields a firmer, more repeatable spring seat that benefits tuning and setup work.

Setup and fitting recommendations

Clean the shock shaft and inspect the top cap before installation to ensure correct seating. When installing the 3RACING 3RAC-DP01/PK, verify spring alignment and retest your damping settings, as precise seating can change perceived stiffness.
