Dual-rate lowering coil springs improve the handling, ride quality and stance of your classic car. The dual rate feature gives you the best of both worlds. The “soft” spring section helps your car to transition over small road irregularities with comfort. As the vehicle further compresses the spring such as when encountering large bumps and high cornering loads, the springs transition to the firmer spring rate to support aggressive bump and body roll movement. StreetGRIP coil springs are CNC cold-wound from high tensile premium steel by then powder-coated for long-lasting, consistent operation. Using our exclusive test track, Ridetech works closely with Hyperco, its technology partner to develop custom dual rates to ensure the best possible handling and ride quality.
Fitment includes:
| Initial Rate | Secondary Rate | |
| Small Block | 480 | 700 |
| Big Block | 518 | 800 |
