The Detroit Speed track bar and shock relocation are designed to improve the cornering and ride quality of your lowered 1967-1972 GM C10 truck. The adjustable track bar features cross-axis bushings and is relocated to reduce lateral axle movement. Roll center height is adjustable for fine-tuning the handling of your truck. Relocated Shock mounts provide proper shock travel and improved control for lowered trucks while maintaining excellent ground clearance. Included non-adjustable drop shocks are designed for trucks lowered 4-inches or more.
