UMI Performance 3627-R Lower Control Arms with Roto-Joint Technology

UMI Performance's 3627-R boxed lower control arms deliver bind-free performance and improved handling through advanced Roto-Joint spherical bearing technology. Engineered for street and track use, these control arms eliminate the flex and deflection common with factory rubber bushings while maintaining a quiet, comfortable ride.

Key Features:

• Roto-Joint spherical bearings on both ends for maximum suspension articulation and travel
• Constructed from 3" x 1-1/2" x 1/8" (0.120" wall) rectangular steel tubing for superior strength
• CNC machined drawn-over-mandrel bushing holders ensure precise fit and alignment
• MIG and TIG welded construction with welded end caps to prevent debris intrusion
• Reinforced sway bar mounting holes with TIG-welded 0.120" steel sleeves
• Greaseable Roto-Joints with delrin-lined races provide 28 degrees of unrestricted movement
• Durable powder coat finish resists corrosion and wear
• Ships fully assembled and ready to install using OEM hardware

The Roto-Joint design uses a pivot ball lined with a greaseable delrin race that absorbs shock and road noise while allowing low-friction operation. This technology eliminates control arm flex and bushing deflection, resulting in improved traction, reduced wheel hop, and precision handling. Perfect for autocross, road racing, or spirited street driving, these control arms offer competition-level performance without sacrificing daily drivability.
