Description
Performance Lowering Coilover Kit. The Belltech Coilover Kit is engineered to enhance the aesthetics and performance of your truck by lowering the ride height between 1 and 3 inches. This kit improves ride quality, reduces body roll, and elevates handling, making it an essential upgrade for those seeking a sportier feel and enhanced vehicle dynamics. Designed specifically for GM trucks, it ensures compatibility and optimized performance.
Construction and Appearance. This coilover kit features high tensile steel coil springs that are powder coated to resist dirt and corrosion, providing long-lasting durability. Included are Belltech’s Street Performance dampers, precisely tuned for optimal damping across adjustable ride heights. The kit utilizes a progressive rate polymer open cell bump stop with packers to fine-tune bump engagement and reduce road harshness, blending functionality with robust, refined design.
Installation. The installation process is straightforward and does not require drilling, offering an easy and secure fit. While professional tools may be necessary for suspension disassembly, the kit is designed as a direct bolt-on upgrade without complicated modifications.
Application. This coilover kit fits 2019-2026 Sierra 1500 models, excluding AT4 and Denali trims. It is not compatible with models featuring ARC or Magnetic Ride Shocks or factory 2-inch lifts such as the Chevy Trail Boss and GMC AT4 & Elevation.
