Competition Engineering Coil-Over Springs 2.5" ID x 12" Long

Right Springs, Right Ride

Competition Engineering Rear Coil-Over Springs are made on precise CNC equipment for superior accuracy and uniform spring rates. Premium grade chrome silicon steel extends durability and maintains correct spring rate and ride height after repeated hard launches. Each spring is computer designed for specific rear end weights to establish the correct ride height and to allow the full range of suspension travel. Maximizing the full potential of the springs based on vehicle weight provides optimum weight transfer, rear axle control and traction. Straight rate springs are best suited for street/strip and race applications were the rear weight of the vehicle does not change. Progressive rate springs adapt to changes in vehicle weight, increasing the effective rate during compression. This makes them ideal for street rods or pro street cars with back seats.
