MFR161041 Tubular upper control arms A-Body Bushed. A-Body control arms cover all A-body Mopars like Dart, Demon, Barracuda, Valiant, Signet, and Duster that have converted to the late '73 thru '76 spindles. Earlier spindles will need to have the hole enlarged to accommodate the larger ball joint provided. Almost any Mopar owner that has lowered their car even slightly by turning the torsion bars down a few turns has come across the problem of not having enough suspension adjustability after doing so. In trying to get the camber back to specs all of the available caster is lost, resulting in less stability at high speeds. MAGNUMFORCE Mopar Tubular upper control arms reduce this by relocating the ball joint further out and toward the rear to begin with which regains that adjustability and more. They also use original style ball joints and urethane bushings in conjunction with the original upper cam adjusters for ease of replacement. Most cars will end up with 3-5 degrees of total positive caster, relative to ride height and the condition of the existing mounts. These control arms cover all A-Body Dodge, Chrysler, or Plymouth Mopars like the Dart, Demon, Barracuda, Valiant, Signet, and Duster that have converted to the late '73 thru '76 spindles. *** the correct spindles (and brakes) can be purchased below *** Click here to get more technical data
