UMI Performance 2033-R Tubular Lower Control Arms for 1982-2002 GM F-Body

UMI Performance's tubular lower control arms for 1982-2002 GM F-Body vehicles deliver bind-free suspension performance with exceptional ride quality. Engineered with UMI's innovative Roto-Joint technology, these control arms provide precision handling for both street and track applications.

Roto-Joint Technology:

The Roto-Joint design features a 4140 chromoly hard chrome-plated spherical ball that rotates within a greaseable delrin race, offering 28 degrees of total unrestricted movement. This eliminates suspension bind while the delrin race absorbs shock and road noise for quiet operation. Unlike traditional rubber or polyurethane bushings that deflect under load, the Roto-Joint maintains its position for improved traction and significantly reduced wheel hop.

Hybrid Bushing Configuration:

This control arm set features Energy Suspension greaseable polyurethane bushings on the chassis end and UMI's swivel Roto-Joint on the axle end—an ideal setup for street performance enthusiasts. The polyurethane bushings absorb additional road noise and shock before it reaches the passenger compartment, while the Roto-Joint ensures the rear axle can articulate freely during aggressive cornering, autocross, or road racing.

Key Features:

• Fully TIG welded construction from 1.500" x 0.120" DOM mild steel tubing
• Swivel Roto-Joints pre-installed and ready to bolt on
• Uses OEM mounting hardware for direct replacement
• Greaseable polyurethane bushings and Roto-Joints for low maintenance
• Adjustable and 100% rebuildable Roto-Joint design
• Durable powder coat finish for long-lasting protection
• Shipped fully assembled for easy installation
• Includes spanner wrench for Roto-Joint adjustment and servicing

Serviceability:

The Roto-Joint is fully rebuildable and adjustable using the included spanner wrench. As the delrin race wears over time, simply tighten the adjusting ring to apply more pressure. The delrin race can be easily replaced if complete wear occurs, ensuring long-term performance and value.

Designed for street performance and enthusiast driving, these control arms allow your suspension to articulate correctly while maintaining comfortable daily driving characteristics.
