Introducing our NEW 5TH-COIL-SPRING featuring dynamic rate control, engineered to increase grip using multiple rates throughout the acceleration curve. The progressive design of the 5th coil delivers maximum grip utilizing a 250lb inch primary spring rate during the first 2 inches of travel, reducing drivetrain shock and increasing initial bite. Rate smoothly transitions to activate the secondary 425lb inch coils, which provide a consistent, planted feel throughout acceleration, reducing “wheel spin” and resulting increased traction lap after lap.
Each 5TH-COIL-SPRING is manufacture by Eibach in the USA with legendary quality and proprietary high-tensile, chrome-silicon spring wire to ensure consistent performance , year after year.
