UMI Performance 73-77 GM A-Body Boxed Rear Lower Control Arms

UMI’s boxed rear lower control arms are a bulletproof addition to your car. Suitable for street, strip or corner carving, these arms minimize suspension deflection for a crisp handling setup and less wheel hop. Sway bar mounting holes are reinforced with TIG welded sleeves to allow factory style sway bar mounting while the included shim allows the sway bar to sit at factory height. UMI’s boxed control arms are CNC machined for accuracy and assembled with high quality greaseable polyurethane bushings.
