The Serpent 411189 Shock Rocker helps you refine shock articulation on the S120L chassis to improve mid corner balance and exit traction. It offers predictable movement so you can tune damping and spring rates with clearer results. The unit is made to maintain its shape under repeated stress for reliable setup comparisons.
Manufactured using robust components, this rocker supports sustained use during intense sessions. The stable construction helps preserve suspension geometry which reduces unexpected handling shifts. It is a useful upgrade for enthusiasts focused on consistent results at the track.
Engineered for S120L compatibility, the rocker replaces the original part with minimal modification required. Fitment is straightforward for those familiar with basic chassis work, and checking alignment after installation ensures the shocks operate as intended. A correct fit keeps steering sharp and the car responsive.
