Threaded coil-over spring perches allow vehicles that would normally have fixed location spring perches to gain some of the benefits of racing developed tuning techniques.

KONI offers several coil-over sleeves and individual components to allow both street and race cars these performance benefits. The threaded sleeves are designed to mount on fixed platforms or groove located circlips that are perpendicular to the damper body. The threaded sleeves are made of anodized aluminum with threaded specially designed for load carrying and self cleaning properties. All lower perches have a nylon tipped locking set screw to positively lock the perch in place without damaging the threads. Note: Caution should be used in the installation and use of threaded spring perches to be sure not to cause damage to the vehicle from bottoming or topping springs, shocks and suspension parts.
