Description

Leaf springs do much more then simply supporting the weight of the vehicle. They are responsible for locating the axle, setting pinion angle, and controlling rearend movement. This makes them a critical part of the rear suspension. BMR’s leaf springs give a superior option to stock leaf springs that sag, rust, and do little to control axle wrap and wheelhop as they get older. The SP057 feature a 2-inch drop, three leafs, and a 190 lb/in spring rate, which reduces body roll without increasing rear oversteer. This commonly happens with too much spring rate. BMR’s spring design, combined with precise clamp locations give you less wheel hop and more axle control. This design reduces axle wrap, which causes the spring to load and unload. By eliminating this oscillation, wheel hop is minimized and traction is improved. Each spring comes with new bushings in the front and rear. Other companies make you buy rear bushings separately, but BMR includes them. The SP057 leaf springs also come with Teflon antifriction pads for smooth, quiet travel through the spring’s range of motion, which further reduces NVH.

BMR designed the SP057s for street performance, drag race, and handling applications. Lowering springs are not only a great way to add an aggressive look to your 1st-Gen F-body, but they also improve the handling capabilities at the same time. By adding BMR’s 2-inch drop leaf springs, you will lower the rear center of gravity and reduce body roll, which improves handling. New bushings greatly reduce the deflection seen in old worn out bushings. New rubber bushings in the front give you a smooth quiet ride, and the polyurethane rear bushings improve handling.

Combine the SP057 with BMR front lowering springs for a level, aggressive stance with huge improvements in handling and performance.

BMR Suspension’s SP057 lowering leaf springs are available with a heavy-duty black coating for corrosion resistance. Installation time is about 2-3 hours. Proudly made in the U.S.A.
