The RACE OPT Progressive Dynamic Spring - High Response is built for hobbyists who need a predictable spring curve. Its 2.5 to 3.3 progressive characteristic helps control weight transfer and improves chassis balance under load.
The coil geometry delivers gradual stiffening as the shock compresses so the car remains composed over successive bumps and during braking transitions.
Fitting these springs is simple for anyone familiar with shock rebuilds. Verify your shock dimensions and choose appropriate preload to match your chassis setup.
