Product Details

UMI Performance's 4044-R rear upper control arms are engineered to deliver precision handling and improved suspension performance for street and track applications. These tubular control arms feature UMI's proprietary Roto-Joint technology, offering bind-free articulation and quiet operation that outperforms factory rubber and aftermarket polyurethane bushings.

Roto-Joint Technology:

The installed spherical Roto-Joints feature a greaseable delrin race that provides 28 degrees of total unrestricted movement, allowing the suspension to articulate correctly while absorbing shock and road noise. This design eliminates binding, reduces friction, and maintains a comfortable ride quality while delivering race-proven performance for autocross, road racing, and high-performance street driving.

Heavy-Duty Construction:

  • Constructed from 1.500" x 0.120" DOM (Drawn Over Mandrel) mild steel tubing for exceptional strength
  • CNC machined mounting plates fabricated from 0.250" thick mild steel for precision tolerances
  • Durable powder coat finish for long-lasting corrosion resistance
  • Direct bolt-on replacement using OEM hardware

Performance Benefits:

  • Minimizes wheel hop during hard acceleration
  • Improves cornering stability and precision
  • Enhances track consistency and lap times
  • Allows proper rear suspension articulation and free movement
  • Greaseable design for easy maintenance and long service life

Shipped fully assembled and ready to install, these control arms represent some of the most robust suspension components available. The combination of heavy-duty construction and innovative Roto-Joint technology makes them ideal for both daily-driven vehicles and dedicated track machines.
