RACE TECH Progressively Wound Shock Spring - Gray - P20 - Spring Rate 454 lbs/in SRSP 6326P20

Rear suspension that's constantly harsh or prone to bottoming compromises both comfort and control—especially under demanding track conditions. The RACE TECH Progressively Wound Shock Spring solves this with a design that firms up progressively, delivering a compliant ride under normal loads while resisting bottoming when you need it most. If you're running a linkless PDS system or simply tired of tuning suspension geometry to chase a balanced setup, this spring offers a straightforward mechanical solution.

Built from premium chrome silicon spring steel, each spring is shot-peened and heat-treated to prevent sacking and maintain consistent performance over thousands of cycles. The progressive rate means the spring resists initial compression softly, then stiffens significantly as deflection increases—giving you the best of both worlds without sacrificing either extreme.
