Product Details
Superior’s single U donut suspension spring booster is designed to boost and restore lift to sagging coil car springs. The strong rubber U-shaped coil spring booster adds firmer support by providing an extra 1″ of lift when installed at the top or bottom of the spring. Crafted from thick rubber 1/2″ in height, this coil spring helper reduces bottoming out and jarring on rough surfaces, giving you a smoother ride. Adding 2 of these Spring boosters per coil spring is recommended for maximum effect.
