BMR Suspension Upper Control Arms DOM On-Car Adjustable Polyurethane Bushings

BMR Suspension on-car adjustable upper control arms are built from DOM (drawn-over-mandrel) steel tubing. They are designed to improve rear suspension control, traction, and durability in street, strip, and performance applications. Many drivers also call them adjustable upper arms or rear upper control arm kits. They replace the factory stamped or non-adjustable arms and let you tune the suspension geometry.

Key Features:

• DOM tubing construction: Drawn-over-mandrel steel tubing gives a strong, consistent, high-strength arm that resists flex and bending under hard launches and cornering.
• On-car adjustability: You can change the arm length without removing the arm from the vehicle. This makes it easier to set pinion angle and fine-tune rear suspension geometry for your driving style.
• Polyurethane bushings: Polyurethane bushings reduce the deflection found in soft factory rubber. They improve wheel hop control, throttle response, and handling feedback.
• Performance upgrade over stock: Compared with factory arms, they give more precise axle location and better power transfer to the pavement.
• Bolt-on installation: They are designed to replace the factory arms with common hand tools and no cutting or welding.

BMR Suspension is a well-known maker of chassis and suspension components for performance vehicles. These upper control arms suit enthusiasts who want a durable, adjustable upgrade for daily driving, autocross, or drag racing.
