Calmax Control Arms frankly were born to solve the wheel clearance problems caused by drop spindles. Like spindles you keep your full suspension travel (factory ride), but unlike spindles you can run any wheel & tire combo that is designed for a C1500. Also unlike spindles you can get more than 2" drop without coils, here you get 3" with the factory coil spring!
All of these Calmax Control Arms have new ball joints and urethane bushings installed and are packaged with new swaybar end-links. We have a 2″, 3″, and 4″ model, with the 2″and 3″ arms using the factory coil spring. The 4″ control arm is actually a 2″ drop arm with the ball joint angles and overall length designed to work specifically with our 2″ drop coil spring. What this means is if you want only a 2″ drop use the 2″ arm and if your going to add a 2″ coil spring to get a total of 4″ use the 4″ control arm for best results!
