UMI Performance 3615-B Boxed Rear Lower Control Arms for 1978-1996 GM B-Body

The UMI Performance 3615-B Boxed Rear Lower Control Arms are engineered to transform the handling and traction of your 1978-1996 GM B-Body vehicle. These heavy-duty control arms replace weak factory stamped steel components that are prone to flex, bushing deflection, and rust—all of which contribute to poor handling and traction loss.

Key Features:

• Boxed steel construction for superior strength and rigidity compared to stock stamped arms
• Energy Suspension polyurethane bushings provide excellent ride quality while reducing traction loss
• Grease-able bushings for long-lasting, quiet operation and easy maintenance
• Reinforced sway bar mounting holes accommodate all sway bar sizes
• Durable powder coat finish for corrosion resistance and long-lasting appearance
• Direct bolt-on replacement—uses OEM hardware for straightforward installation

These boxed lower control arms are designed to minimize wheel hop, improve cornering ability, and enhance track consistency whether your vehicle is a weekend cruiser or a dedicated track machine. The polyurethane bushing setup offers the perfect balance between street comfort and performance enhancement, making them ideal for street driving, drag racing, or road course applications.

Applications: 1978-1996 Chevrolet Caprice, 1994-1996 Chevrolet Impala SS, 1978-1996 Buick Roadmaster, 1978-1988 Buick LeSabre, 1978-1981 Pontiac Bonneville and Catalina.
