Precision Handling for Your Classic GM A-Body

Transform the handling and launch characteristics of your 1964-1967 GM A-Body with the BMR Suspension On-Car Adjustable Upper Control Arms. Designed for street performance, drag racing, and road course applications, these arms replace the weak, flexible factory stamped steel units that suffer from excessive bushing deflection.

Key Features and Construction

• Heavy-Duty Construction: MIG-welded 1 1/4-inch DOM steel tubing for maximum structural integrity.
• On-Car Adjustability: Features a CNC-machined chromoly center adjuster for quick pinion angle or alignment changes without removal.
• Performance Rod Ends: Equipped with heavy-duty Teflon-lined rod ends and CNC-machined 7075 billet aluminum spacers.
• Durable Finish: Finished in a sleek, long-lasting Black Hammertone powdercoat.

By eliminating the soft rubber bushing deflection inherent in stock components, these BMR control arms ensure your power is transferred directly to the pavement rather than being absorbed by the suspension. Whether you are building a dedicated drag car or a spirited street cruiser, this upgrade provides the rigidity needed for consistent performance. Installation typically takes 2-3 hours, making this one of the most effective suspension modifications for your classic vehicle. Proudly designed and manufactured in the U.S.A., these arms are the gold standard for A-Body suspension tuning at GGCRACING.
