UMI Performance Tubular Lower A-Arms Control Arms

UMI Performance Tubular Lower A-Arms are performance replacement lower control arms built to improve handling, strengthen the suspension and give a smoother ride than stock stamped-steel arms. UMI designs and builds them in the USA, and they are a popular upgrade for street, strip and track.

Key Features:

• DOM steel tube construction: The arms are fabricated from DOM steel tubing, which adds strength and rigidity over factory arms.
• Precision fit: Tube ends are CNC machined or notched, and the arms are built in a jig so they bolt on accurately.
• TIG-welded: Critical areas are TIG welded for strength and a clean appearance.
• Greaseable bushings: Depending on the part number, the arms use greaseable polyurethane bushings for a smooth, quiet ride. Some applications offer Delrin bushings for more precision and less friction.
• Ball joint angle: On front lower arms, the ball joint mount is angled to work with lowered vehicles and to add wheel and tire clearance.
• Spring compatibility: Front lower arms are designed to work with factory springs, lowering springs and most coil-over setups.
• Durable finish: Arms are powder coated for corrosion resistance and appearance.

Rear lower control arms in the line help reduce wheel hop and improve cornering and traction consistency. Adjustable versions let you fine-tune rear axle position. UMI Performance arms are built for durability and are tested on the street, drag strip and skid pad.
