About this part

Rear control arms are essential suspension upgrades for GM vehicles. Stock control arms are prone to bushing deflection and rusting, leading to traction loss and poor handling. Our boxed control arms offer improved performance for both weekend cruising and track use. The included polyurethane bushings outperform OEM rubber, enhancing ride quality and reducing traction loss. These direct bolt-on control arms minimize wheel hop, enhance cornering, and promote track consistency. They are designed with provisions for both stock and aftermarket sway bars, with reinforced sway bar holes for added durability. Constructed with 0.120" wall thickness rectangular tubing, CNC machined bushing holders, and MIG welded end caps for protection against road debris. Installation is straightforward, using OEM hardware and taking approximately 1 hour. Detailed installation instructions are included for convenience.

  • Built with 0.120" Wall Thickness Rectangular Mild Steel Tubing
  • Grease-able High Quality Bushings with Grease Fittings
  • CNC Machined for Precision Tolerances and Accuracy
  • Durable Long Lasting Powder Coat finish
  • MIG Welded DOM Steel Bushing Holders
