UMI Performance Upper Control Arm for GM B-Body

UMI Performance upper control arms for the GM B-Body are direct-replacement rear upper control arms (also called trailing arms). They are built to reduce wheel hop, improve cornering and help keep traction consistent at the track and on the street. They replace the factory arms, which are prone to flex and wear.

Key Features:

• Direct bolt-on replacement for the factory arms
• Adjustable designs let you change pinion angle without removing the arms from the car
• 4140 chrome-moly adjusters and tube adaptors for strength in high-stress areas
• TIG-welded construction for durability
• Grease-able polyurethane bushings
• Durable powder-coat finish to resist corrosion
• Designed and manufactured in the USA

UMI Performance is known for its GM suspension upgrades. Each arm is built to give a firmer, more controlled rear suspension that works for street driving, strip use and handling builds.
