Product details

Belltech Torsion Bar Keys make lowering or leveling your torsion bar equipped IFS truck or SUV simple, safe and cost effective. After broaching the high strength ductile iron casting to the appropriate degree that allows retention of the factory spring rate and ride quality, each key is then E-coated for a long durable corrosion free life. Whether using lowering or leveling keys, height adjustment ranges typically allow from 1 to 3" of adjustment. Belltech's adjustable torsion bars keys are a direct replacement to the oem key for an easy hassle free solution for a new lowered look.
