Boxed control arms boost traction, ride quality, and durability.

Upgrade your B-Body with UMI boxed control arms for better traction, ride quality, and strength. Made from 0.120" wall tubing with grease-able polyurethane bushings, they reduce deflection and wheel hop. Hardware kit sold separately.

UMI Performance control arms are an excellent upgrade for your classic B-Body, ideal for restoration projects, street cars, cruisers, or drag racers. These boxed control arms directly replace stock stamped steel versions, which can rust and weaken over time. The included grease-able polyurethane bushings enhance ride quality and reduce bushing deflection compared to stock rubber bushings, minimizing body roll, increasing traction, and eliminating wheel hop. Constructed with 0.120" wall thickness rectangular tubing, CNC machined drawn over mandrel bushing holders, and MIG welded end caps to block debris, these control arms also feature correct spring perches compatible with factory springs. UMI Performance offers a hardware kit for installation that includes all necessary Grade 8 hardware except shock mount bolts.
