BMR Rear Performance Lowering Springs - 1" Drop - Red (SP017R) - 1964-1966 GM A-Body
Drop the tail end of your classic intermediate muscle car and improve its rear suspension dynamics with the Rear Performance Lowering Springs (SP017R) from BMR Suspension. Custom-tuned for early 1964-1966 GM A-Body platforms, this pair of rear coils lowers the rear suspension by a precise 1 inch. Perfect for custom configurations, leveling out an uneven stance, or matching specific front setups, this kit effectively brings down your vehicle's center of gravity. This results in a sleek, athletic rear profile, significantly flatter cornering, and lessened rear-end squat during hard acceleration, all while maintaining a smooth and responsive street ride.
Every rear spring in the SP017R kit is engineered from premium high-tensile chrome silicon spring wire and cold-wound on high-precision CNC coiling machinery to guarantee absolute consistency across the axle. BMR relies on a strict manufacturing regimen to ensure maximum durability: each coil is pre-compressed solid twice at the factory to set its permanent height, stress-relieved at 750°F, and shot-peened to resist fatigue over time. Rated at a calibrated 175 lb/in, these linear springs keep the rear suspension stable and tracking predictably under load. Covered in a bright red powder coat and 100% computer load-tested, this rear set carries a lifetime warranty against spring sag.
