RACE TECH Progressively Wound Shock Spring - Orange - P15 - Spring Rate 195 lbs/in - 285 lbs/in SRSP 6326P15

Rear suspension that punishes you on every bump doesn't belong on a track car—or a street machine. This RACE TECH progressive spring solves the dual problem of harshness and bottoming by ramping up resistance as the suspension compresses, giving you a compliant ride over small inputs while maintaining iron-fisted support under heavy load. If your current setup leaves you choosing between comfort and bottoming out, this is the solution.

The progressive design means the spring rate starts at 195 lbs/in and increases to 285 lbs/in through the travel, eliminating that harsh initial bite while keeping the rear planted when it matters most. Built from chrome silicon spring steel with shot-peening and heat-treatment, this spring is engineered to last through countless heat cycles and maintain its preset characteristics without sagging or permanent deformation.
