CPP’s quality upper and lower tubular control arms are welded for maximum strength and visual impact. The lower control arms have a helical stamped coil spring mount, just like they did from the factory, which secures the coil spring into the lower control arm. The coil mount has been improved to make installation even easier. The lower shock mount is incorporated into the stamped coil plate and will also accept QA-1 coil over and Ridetech Shockwave™ units as well. This stamping is welded around its entire perimeter. All arms that contain cross shafts are preassembled with the cross shafts and pivot sleeves and have a safety feature that captures both sides of the bushing, unlike the originals that were only retained on the one side of the bushing under the head of the bolt. This unique feature allows full control and virtually no flex on the control arm when cornering.
