UMI Performance Upper Control Arm GM Rear Suspension

The UMI Performance rear upper control arm for GM vehicles is a suspension upgrade for drivers who want better rear-end control. It is also sold as a rear upper trailing arm or rear suspension link. It replaces the factory arm and suits street, strip, and autocross use.

Key Features:

• Strong construction: UMI builds its control arms from tubular steel with welded, precision-formed ends.
• Better rear suspension control: A stiffer arm limits unwanted flex and deflection. This helps keep the rear axle located under hard acceleration, braking, and cornering.
• Bushing options: UMI control arms are commonly offered with polyurethane or spherical bearing ends. These are meant to cut deflection compared with stock rubber bushings.
• Bolt-in installation: The arm uses the factory mounting locations, so no cutting or welding is normally needed.
• Durable finish: A protective coating helps resist corrosion and wear.
