StreetGRIP front coil springs improve the handling, ride quality and lower the stance of your 1955-1957 Tri-Five Chevy including Bel Air, 150 and 210 models. They feature a dual rate design which gives your classic the best of both worlds. The “soft” spring section helps your car to comfortably transition over small road irregularities. As your car’s springs further compress — such as when encountering large bumps and cornering loads — the design transition to the firmer spring rate. StreetGRIP coil springs are CNC cold-wound from high tensile premium steel by then powder-coated for long-lasting, consistent operation. Ridetech works closely with Hyperco, our technology partner, to develop springs for exceptional performance and comfort.
