UMI Performance 3655-R Lower Control Arms for Chevrolet B-Body

The UMI Performance 3655-R lower control arms are engineered to replace factory stamped control arms on classic Chevrolet B-body vehicles. These boxed control arms offer a direct bolt-in installation and provide significant performance improvements for restoration projects, street cars, and drag racing applications.

Construction and Design:

• Manufactured from 1/8" wall thickness USA rectangular tubing for superior strength
• DOM (drawn over mandrel) bushing holders for precise fitment and durability
• Reinforced sway bar mounting holes to prevent deformation
• Integrated spring perches and clips compatible with factory or lowering springs
• Boxed design eliminates the weakness of factory stamped steel construction

Performance Benefits:

• High-quality greaseable polyurethane bushings improve ride quality and handling
• Reduced bushing deflection compared to factory rubber bushings
• Minimizes body roll during cornering and acceleration
• Increased traction through improved suspension geometry
• Eliminates performance degradation from aged, cracked factory bushings

Hardware Kit Option: UMI offers an optional hardware kit that includes all necessary Grade 8 mounting hardware for installing one pair of rear lower control arms. The kit provides new nuts for the shock mount bolt, though the OEM shock bolt must be reused.

Designed and manufactured in Philipsburg, Pennsylvania, USA. These control arms address common issues with aging factory components including rust weakening and bushing deterioration that compromise ride quality and vehicle performance.
