ReadyLift 3.5"F / 1"R SST Lift Kit

 

The ReadyLIFT 3.5 inch F / 1 inch R SST Lift Kit is designed for heavy-duty GM truck customers who want more front ride height, a confident stance, and larger tire clearance while keeping towing and work-truck usability in mind. The system uses ReadyLIFT Smart Suspension Technology to raise the front suspension without permanently modifying the truck. It is a practical lift for customers who want an HD truck to look stronger, clear more tire, and remain dependable for everyday work.

Forged torsion keys are a key part of the front lift package. They are indexed for the lift range so the truck can gain front height without simply over-cranking the factory torsion bars beyond a useful operating range. The kit also includes CNC-machined differential drop spacers on 4WD applications to help keep the front CV axles operating at safer angles after the ride height change.

Heavy-duty tubular steel upper control arms add the strength and geometry support expected on a lifted HD truck. The system also includes stronger replacement tie rod assemblies to improve steering hardware durability where larger tires, heavy loads, and rough roads can place additional stress on the front end. These components help the lift feel more complete than a basic torsion key setup.

The rear uses an OE-style 1 inch cast iron lift block package with new U-bolts and hardware. That rear lift helps preserve a functional stance while keeping the truck useful for trailers, bed loads, tools, and weekend equipment. The cast block design resists the deformation concerns associated with weaker materials and supports the heavy-duty character of the vehicle.

This system is a strong choice for customers who tow, haul, run jobsite roads, drive long highway miles, or want to clear up to a 34 inch tire package with the correct wheel setup. It provides a lifted stance without requiring cutting or welding on supported applications. The result is an HD truck that looks more capable and has the suspension support needed to remain composed.

Whether customers are upgrading for towing stance, larger tires, work use, daily driving, or a stronger heavy-duty appearance, the ReadyLIFT 3.5 inch F / 1 inch R SST Lift Kit delivers practical lift height with HD-focused suspension hardware. Now Available at LEER!
