Suspension Lift Kit. The ReadyLIFT 3.50-Inch Front / 1-Inch Rear SST Suspension Lift Kit with Fabricated Control Arms raises the suspension of GM Silverado and Sierra 2500 HD trucks to improve ground clearance and accommodate larger tires up to 34 inches in diameter. This bolt-on kit enhances vehicle stance and off-road capability without permanently modifying the truck’s structure, making it ideal for owners seeking a moderate lift while maintaining factory ride quality.

Construction and Appearance. Featuring heavy-duty tubular steel upper control arms and forged torsion keys with shock extensions, this kit delivers exceptional strength and durability. The rear lift blocks are OEM style cast iron with precision CNC-machined differential drop spacers for 4WD models, ensuring reliable performance and correct driveline angles. Components have a robust finish designed to resist deformation under load.

Installation. Installation is moderately complex and recommended for professionals or experienced mechanics. The kit installs without cutting, welding, or drilling of OEM parts, preserving the integrity of the vehicle's original components. Note that use of longer front shocks is required but they are not included with the kit.

Application. Designed specifically for 2011 to 2019 GM Sierra 2500 HD trucks with single rear wheels. It is not compatible with trucks equipped with the factory TOP overload spring camper package. Single cab configurations have not been validated for fitment or drivability.
