ReadyLIFT 2-Inch SST Suspension Lift Kit with Upper Control Arms (25-26 Silverado 1500 Trail Boss)Find parts that fit my vehicle

Precision Suspension Upgrade. The ReadyLIFT 2-Inch SST Suspension Lift Kit with Upper Control Arms provides a seamless 2-inch front lift combined with the factory 2-inch lift, plus a 1-inch rear lift to enhance off-road capability and aggressive styling. Designed specifically for factory-lifted 2025-2026 GM 1500 AT4 and Trail Boss trucks, this kit addresses common issues encountered with traditional leveling kits on vehicles that already have factory front lifts. It ensures proper suspension geometry and prevents binding issues for improved driving performance.

Construction and Components. The kit features CNC-machined billet aluminum top spacers and pre-load spacers engineered for durability and precise fitment. Heavy-duty tubular upper control arms come equipped with 1-ton ball joints and maintenance-free TCT pivot bushings. The rear lift includes 3-inch tall OE-style cast iron lift blocks with new longer U-bolts and rear bump stop extension cups. All components are finished for corrosion resistance and long-term reliability.

Installation. Installation involves a bolt-on design requiring no drilling and is recommended to be performed by certified mechanics. The process typically takes about 4.5 hours plus alignment. After installation, adjustments to headlamp aiming and recalibration of Advanced Driver Assistance Systems may be necessary due to suspension modifications.

Application. This kit fits 2025-2026 GM Silverado 1500 Trail Boss and AT4 4WD models equipped with the factory 2-inch front lift and traditional steel rear leaf springs. It is not compatible with Sierra AT4X, Silverado ZR2 Edition vehicles, or those equipped with rear composite mono-leaf springs.
