BMR Suspension rear lowering springs for 1964–1966 GM A-body provide a vehicle-specific 1 inch drop and a variable spring rate aimed at better cornering stability and a smooth ride. Springs are CNC-wound from chrome silicon steel, compressed at the factory for a permanent set, stress-relieved and shot-peened, then computer-tested. Red powdercoat protects the finish and BMR supports them against sag with a lifetime warranty.
