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

The UMI Performance 3655-B lower control arms are a direct bolt-in replacement designed for classic Chevrolet B-body vehicles. These boxed control arms offer a significant upgrade over factory stamped control arms that are prone to rust, weakening, and deterioration over time.

Key Features:

• New manufactured boxed control arm construction with 1/8" wall thickness USA rectangular tubing
• High-quality greaseable polyurethane bushings that improve ride quality and vehicle performance
• DOM (Drawn Over Mandrel) bushing holders for superior strength and durability
• Reinforced sway bar mounting holes for enhanced structural integrity
• Integrated spring perches and clips compatible with factory springs or lowering springs
• Polyurethane bushings reduce deflection, helping to minimize body roll and increase traction
• Designed and manufactured in Philipsburg, Pennsylvania USA

Optional Hardware Kit:

UMI offers an optional hardware kit (sold separately) that includes all necessary Grade 8 mounting hardware for installing one set of rear lower control arms. The kit includes new nuts for the shock mount bolt, though customers must reuse the OEM shock bolt.

Ideal for restoration projects, street cars, or drag racing applications, these control arms address the common issues of deteriorated factory rubber bushings that dry rot, harden, and crack over time. The upgrade to polyurethane bushings provides superior performance and longevity compared to original equipment.
