UMI Performance 5015-B Rear Lower Control Arms for 1971-1980 GM H-Body

UMI Performance's rear lower control arms are engineered specifically for 1971-1980 GM H-Body vehicles as a direct bolt-in replacement for factory control arms. These performance-oriented control arms feature lightweight tubular construction designed to minimize wheel hop, improve traction, and deliver consistent track performance.

Key Features:

• Fabricated from 1.250-inch drawn over mandrel (DOM) mild steel tubing for superior strength
• CNC machined components with full TIG welding for maximum durability
• Solid construction eliminates flex found in factory control arms
• Greaseable Energy Suspension polyurethane bushings minimize deflection
• Zinc-plated steel sleeves and grease fittings included
• Easy bolt-on installation using OEM hardware—no drilling required

The rigid tubular design provides a significant upgrade over stock stamped steel arms, reducing unwanted suspension movement while maintaining proper geometry. Energy Suspension bushings offer the perfect balance between performance and street comfort, with grease fittings ensuring long-term serviceability.
