Description
SuperCoils® are heavy duty replacement coil springs, designed to remedy sagging and overworked original equipment front and rear suspension coil springs. SuperCoils have a linear/constant spring rate consistent with other coil springs. SuperCoils actually replace original equipment, different from SuperSprings or SumoSprings that work in conjunction with and enhance original equipment.

Wade Gingerich –
SuperSprings was easy to deal with during the order process, the product arrived quickly and was a perfect fit. It also functioned as described, I recommend them to anyone who pulls a lot of heavy weight.
