UMI 4043-R 64-72 A-Body Dbl. Adj. Lower Arms, Roto-Joints, Red

UMI's double adjustable lower control arms utilize our Roto-Joint technology for a bind free performance, quiet ride quality, and also offer on car adjustment. The control arms can be adjusted longer or shorter moving the rear end back or forward to squeeze those larger tires in the fender wells. Adjustable control arms are also recommended for most aftermarket rear end installs to center the rear end and prevent tire rubbing. The control arms are fabricated from 1-1/2" drawn over mandrel tubing with TIG welded chromoly threaded tube adapters for the utmost in strength and performance. The threaded ends feature left and right hand threads for easy on car adjustments, simply loosen the jam nuts and turn the wrench to make adjustments. Both control arms feature the correct provisions for adding a stock or aftermarket sway bar. Sway bar holes are reinforced with a 0.120" wall thickness steel sleeve that TIG welded and sanded into place. This control arm set features Roto-Joints on both sides of the control arms. This is designed for maximum performance and suspension travel. The installed Roto-Joint is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, more than adequate for a bind free, low friction operation. The Roto-Joint design improves performance over the factory rubber and aftermarket polyurethane bushings by allowing the suspension to articulate correctly, and provide precision handling. The installed UMI Roto-Joint allows rear end free movement when high handling, auto cross or road race is a concern while still being a 100% streetable setup. The installed delrin race, which lines the spherical ball, absorbs shock and road noise for a quiet and smooth operation but also works excellent as a solid bushing drag race control arm. All Roto-Joints are greaseable and low maintenance making an excellent street setup for your cruiser or race car!
