UMI Performance 3041-R Boxed Lower Control Arms with Roto-Joints

The UMI Performance 3041-R boxed lower control arms combine advanced Roto-Joint technology with precision engineering to deliver bind-free suspension performance and exceptional handling for street and track applications. Designed to eliminate control arm flex and bushing deflection, these control arms provide improved traction, reduced wheel hop, and precision handling while maintaining a comfortable ride quality.

Key Features:

• Constructed from 3" x 1-1/2" x 1/8" (0.120" wall thickness) rectangular steel tubing for superior strength
• UMI Roto-Joint spherical bushings with delrin-lined pivot balls providing 28 degrees of unrestricted movement
• Greaseable Energy Suspension polyurethane bushings on chassis side for reduced road noise and vibration
• CNC machined drawn-over-mandrel bushing holders for accurate tolerances and perfect fitment
• MIG and TIG welded construction with welded end caps to prevent road debris intrusion
• Reinforced sway bar mounting provisions with TIG-welded 0.120" steel sleeves
• Durable powder coat finish for long-lasting corrosion protection
• Ships fully assembled and ready to install using OEM hardware

The hybrid bushing design pairs polyurethane bushings at the chassis mounting point with Roto-Joints at the rear axle connection. This configuration allows the softer polyurethane to absorb road shock and noise before reaching the passenger compartment, while the Roto-Joints enable proper suspension articulation for improved handling. The delrin-lined spherical bearings provide low-friction operation and absorb shock for quiet performance on both street and track-driven vehicles. Compatible with stock and aftermarket rear sway bars.
