UMI Performance 2034-R Tubular Rear Lower Control Arms GM F-Body 1982-2002

The UMI Performance 2034-R tubular rear lower control arms are engineered for 1982-2002 GM F-Body vehicles, delivering precision handling and bind-free suspension performance. These control arms utilize UMI's proprietary Roto-Joint technology to provide superior articulation over factory rubber and aftermarket polyurethane bushings, making them ideal for street driving, autocross, and road racing applications.

Roto-Joint Technology:

The Roto-Joint design features a 4140 chromoly hard chrome-plated spherical ball that rotates within a greaseable delrin race, allowing 28 degrees of total unrestricted movement. This pivot system eliminates suspension bind while absorbing shock and road noise for quiet, comfortable street operation. Unlike softer bushings that deflect under load, the delrin race maintains its shape to improve traction and significantly reduce wheel hop during hard driving.

Key Features:

• Constructed from 1.500" x 0.120" DOM mild steel tubing with full TIG welding
• Roto-Joints installed on both sides for maximum performance and suspension travel
• Greaseable and rebuildable Roto-Joints with adjustable tension via spanner wrench
• Durable powder coat finish for long-lasting corrosion resistance
• Uses OEM hardware for straightforward installation
• Ships fully assembled and ready to install
• 100% streetable while offering race-proven performance

What's Included:

Each set includes tubular lower control arms with pre-installed Roto-Joints and a spanner wrench for adjustment and maintenance. The spanner wrench allows you to tighten the adjusting ring as needed to maintain proper tension on the delrin race, and can be used to disassemble the Roto-Joint for cleaning, inspection, or rebuilding.

The adjustable and rebuildable design ensures long-term serviceability, making these control arms an excellent investment for both cruisers and dedicated race cars.
