Koni Threaded Spring Perch Sleeve Kits

Koni threaded spring perch sleeve kits allow vehicles that would normally have fixed location spring perches to gain some of the benefits of racing-developed tuning techniques. Performance suspension adjustments, such as ride height and corner weighting or weight jacking can be performed with threaded spring perches and individual components. Koni offers several coilover threaded spring perch sleeve kits to allow both street and race cars these performance benefits. These threaded sleeves are made of anodized aluminum and are 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. Show Less
