Suspension Spring Kit - 2 in Lowering - Rear - Steel - Red Powder Coat - GM G-Body 1978-87 - Pair

Lowering Springs

There is nothing like the aggressive look of a car with the right stance! Over time, stock springs sag, get rusty, and simply wear out. BMR's suspension believes the right springs go beyond looks your 1978-1987 G-Body needs to perform, too! All BMR springs are manufactured from chrome silicon high-tensile spring wire, and are cold wound on a CNC coiling machine. The CNC coiling head can adjust the spring diameter in real time to ensure that every spring is exactly the same. This guarantees that your right spring matches your left spring. Every BMR'spring is compressed solid at the factory, not once, but twice. This gives the spring its permanent set, and guarantees no sag. BMR springs are stress-relieved at 750 degrees F, ensuring most stresses induced during the winding process are eliminated. All springs are then shot-peened to eliminate residual surface stresses. Many spring manufacturers skip this step, but BMR insists on this operation as part of our spring manufacturing process.

Additional Information

The SP465 offers plenty of support, keeping the body flat and level in the corners, while remaining soft enough for a comfortable ride on any road.

Many spring manufacturers skip this step, but BMR insists on this operation as part of our spring manufacturing process. Every spring is computer tested as the last step?every spring, not just a sample from each batch. Each spring is loaded in the spring tester at the factory, then compressed and the CNC load cell measures the force for a variety of spring lengths. This allows BMR to offer a LIFETIME WARRANTY against spring sag.

BMR lowering springs are designed to improve handling performance by lowering your ride's center of gravity for tighter suspension and reduced body roll and wheel well gap. Cold-wound from high-tensile strength chrome silicon for a long-lasting, consistent rate without long-term "memory" loss, these suspension components are designed for additional spring rate in the stiffer portion of the coil for perfect handling during aggressive cornering. Dozens of lowering spring models are available with various front and rear drop measurements. Select the springs tailored for fitment on your vehicle.
