With a 400 lb/in spring rate and 10-inch travel capability, this spring provides the stiffness and support required for both street and track applications. The 2.5-inch inner diameter makes it compatible with industry-standard coil-over setups, while the durable silver powder coat resists corrosion and looks clean in the bay.
