Refine Suspension Tuning with RACE OPT Springs

The RACE OPT Progressive Dynamic Spring - High Response is engineered to help RC drivers dial in suspension feel. With a progressive rate from 2.5 to 3.3 these green springs let you adjust mid and end stiffness to achieve more precise handling on technical tracks.

Fitting the RACE OPT springs is straightforward for hobbyists at any level. They suit a wide selection of shock assemblies but check inner diameter and stroke to confirm compatibility before fitting.
