Advanced Suspension Lift. The ReadyLIFT 4-Inch Big Suspension Lift Kit is engineered to enhance ride quality and handling for 1500 Trail Boss and AT4 trucks. This kit increases ride height for improved ground clearance and a more aggressive stance while maintaining superior vehicle control and stability both on and off-road.

Construction and Appearance. Crafted with boxed steel front and rear cross members and a full-width front skid plate made from 3/16-inch plate steel, this kit delivers long-lasting durability and protection. It features fabricated steel differential drop brackets with double gussets and boxed center ribs, along with heavy-duty cast iron lift knuckles designed to retain factory suspension geometry, ensuring strength and a clean, functional appearance.

Installation. Installation requires approximately 10 hours plus wheel/tire assembly and alignment. The process involves no drilling but requires specific hardware including sway bar drop brackets and strut extensions to ensure proper fitment and function. Users should be prepared for trimming certain components when fitting larger tires as specified.

Warranty. This kit comes with a Powertrain Warranty, providing added confidence in performance and reliability.

Application. Designed for 2019-2024 Silverado 1500 Trail Boss and GMC AT4 1500 models, this lift kit is not compatible with rear mono-leaf spring configurations, diesel motor applications, or single cab configurations that have not been validated for fitment and drivability. Use of the Auto 4 Hi feature is not recommended, and 18-inch wheels are generally not advised due to fitment constraints. Late model 2024 and 2025 applications require specific modifications, including the use of U-bolt part number 67-35150UB for 2025 models.
