Product Details

The UMI Performance 4040-B rear tubular lower control arms deliver bind-free suspension performance with streetable comfort. Engineered with UMI's proprietary Roto-Joint technology, these control arms provide precision handling and unrestricted articulation for high-performance driving while maintaining excellent ride quality for daily use.

Key Features:

  • Roto-Joint spherical bearings on both ends for 28 degrees of total unrestricted movement
  • Constructed from 1.500" x 0.120" wall DOM mild steel tubing for exceptional strength
  • Greaseable Delrin race liners absorb shock and road noise while reducing friction
  • Fully TIG welded construction with brilliant powder coat finish
  • Reinforced sway bar mounting holes with 0.120" steel sleeves, TIG welded and sanded flush
  • Uses OEM mounting hardware for direct bolt-in installation
  • Ships fully assembled and ready to install

The Roto-Joint design outperforms factory rubber and aftermarket polyurethane bushings by allowing proper suspension articulation without binding. The spherical pivot ball with greaseable Delrin race provides low deflection for improved traction, making these control arms ideal for autocross, road racing, and aggressive street driving. The result is a 100% streetable setup that delivers race-proven performance with low maintenance requirements.
