AST Suspension Lowering Springs (40mm/40mm) - 1988-1993 Ford Sierra XR 4WD (BEF/BFGC)

The AST Suspension Lowering Springs for the 1988-1993 Ford Sierra XR 4WD (BEF/BFGC) are high-performance coil springs designed to lower the vehicle's ride height by 40mm. Constructed from premium high tensile chromium-silicone wire, these springs are carefully handpicked by AST engineers for their quality and metal consistency. The springs are cold wound, heat treated to enhance hardness and minimize internal stresses, and then individually shot peened, phosphate treated, and powder coated to ensure durability and longevity beyond the vehicle's lifespan. Featuring progressive rates on most applications, these springs improve handling, stability, and aesthetics by reducing body roll and lowering center of gravity.

Designed specifically for the 1988-1993 Ford Sierra XR 4WD models, these springs are a direct replacement for the factory components, offering a performance upgrade suitable for street and spirited driving. They are compatible with vehicles equipped with the BEF or BFGC chassis codes and are intended for use on vehicles with similar specifications. Installation is straightforward as they are bolt-on replacements, providing an effective solution for enthusiasts seeking improved stance and handling. The kit includes the set of lowering springs, with no additional components required for installation.
