UMI Performance Rear Boxed Lower Control Arms

UMI Performance Rear Boxed Lower Control Arms are a durable replacement for the factory rear lower control arms (trailing arms). They suit street, strip and corner-carving use. The boxed design limits suspension deflection, which sharpens handling and reduces wheel hop.

Key Features:

• Boxed rectangular steel tubing: UMI builds these arms from heavy-wall rectangular steel tubing. This is much stiffer than a stamped factory arm.
• CNC machined components: The bushing holders and radius ends are CNC machined for consistent, accurate dimensions.
• Welded construction: The bushing holders are welded for strength. Capped ends help keep debris out of the arm and keep a clean factory appearance.
• Reinforced sway bar mounting: The sway bar holes are reinforced, so the arms can work with a factory-style sway bar setup.
• Greaseable polyurethane bushings: The bushings are meant to hold up in demanding driving and to be easy to maintain.
• Powder coat finish: The durable powder coat resists corrosion and wear.

These bolt-in rear lower control arms are a straightforward suspension upgrade. They improve rear-end stability, traction and handling feel. UMI Performance is a well-known maker of GM-focused suspension components, and it designs and CNC machines its parts in the USA.
