Description
Performance Suspension Upgrade. The Belltech Performance Lowering Kit with Height Adjustable Front Coil-Overs; 2 to 4-Inch Front / 4-Inch Rear lowers your vehicle’s ride height while enhancing handling and style. Designed to replace original equipment suspension components, it provides precise height adjustment and improved control for an optimized driving experience on the road.
Construction and Appearance. Crafted from high-strength ductile iron and cold-formed tensile steel, all components feature powder-coated finishes for long-lasting durability and corrosion protection. The coilovers feature large diameter damper bodies with independent rebound and compression valves for consistent damping performance. Drop spindles and sway bars are engineered for strength and maintain factory suspension geometry throughout.
Installation. Installation requires moderate mechanical skill and bolts directly to the vehicle using OEM top mounts with no drilling required. Always verify wheel clearance since variations in OEM wheel barrel dimensions may exist.
Application. Specifically engineered for the 2019 to 2026 Sierra 1500 models, this kit is not compatible with the AT4 or Denali trims, nor vehicles equipped with Trail Boss packages or Adaptive Ride Control systems. It also requires flat top-plate conversion or round-bend U-bolts when installed on trucks with OEM rounded leaf-spring U-bolts.
