What is the main benefit of the shot-peening process for these springs?

Shot-peening eliminates residual surface stresses in the spring material. This process helps to prevent the formation of cracks and increases the spring's overall durability and lifespan.

How does BMR ensure that the left and right springs are identical?

The springs are cold wound on a CNC coiling machine, which allows for real-time adjustment of the spring diameter. This precise manufacturing ensures that each spring is exactly the same, guaranteeing that your right spring matches your left spring.

Product Details

The SP464 front lowering springs are made from chrome silicon high-tensile spring wire, cold wound on a CNC coiling machine. This process ensures that the spring diameter is precisely controlled, so your left and right springs are identical. Each spring is compressed solid twice at the factory to set its permanent form and prevent sagging over time. They are then stress-relieved at 750 degrees F and shot-peened to remove any residual stresses from the winding process, a step many manufacturers skip but BMR insists on for durability.

These springs are computer tested before leaving the factory, with each spring loaded and compressed to measure its force at various lengths. This rigorous testing guarantees consistent performance and allows BMR to offer a lifetime warranty against spring sag. The SP464 springs are designed to keep the body flat and level during cornering while still providing a comfortable ride on various road surfaces, lowering the front of your 1978-1987 G-Body by 2 inches for an aggressive stance.
