UMI Performance 3662-B Upper Control Arm for GM B-Body - 67-70

The UMI Performance 3662-B is a high-performance upper control arm designed specifically for 1967-1970 GM B-Body vehicles. This direct replacement for the factory arm offers superior adjustability and durability to minimize wheel hop, improve cornering, and enhance track consistency.

Key Features:

• On-Car Adjustability: Unique design allows pinion angle adjustments while the control arm remains installed on the vehicle—no removal required
• 4140 Chrome-Moly Construction: Features heat-treated 4140 Chrome-Moly adjuster and tube adaptors for maximum strength and durability
• TIG Welded: Professional TIG welding ensures structural integrity and long-lasting performance
• Greaseable Polyurethane Bushings: Energy Suspension polyurethane bushings provide superior performance over worn factory rubber bushings
• Durable Powder Coat Finish: Brilliant powder coating protects against corrosion and maintains appearance
• Easy Adjustment: Simple adjustment using left and right-hand threaded adjuster with jam nuts—eliminates need for shims during installation

Application Note: This item is sold individually. Six-cylinder and most small-block GM B-Body vehicles used a 3-link rear suspension (requiring one upper control arm), while big-block vehicles used a 4-link setup (requiring two upper control arms). Please verify your vehicle's configuration before ordering.

When it's time to replace worn factory suspension components, the UMI Performance 3662-B upper control arm delivers the adjustability and quality construction demanded by performance enthusiasts and racers.
