ReadyLift 4.5"F / 2.5"R SST Lift Kit

 

The ReadyLIFT 4.5F / 2.5R SST Lift Kit gives heavy-duty 4WD truck owners a taller, more aggressive stance while keeping the truck practical for daily driving, hauling, and towing. It is designed as an SST suspension upgrade, so the lift height is paired with radius arm correction, track-bar support, sway-bar components, bump-stop control, and application-specific hardware. Customers get a meaningful increase in ride height without moving into a full big-lift system.

This kit is built around heavy-duty fabricated steel coil spring spacers and geometry correction components for the radius arm suspension platform. The front lift raises the truck enough to create clearance for larger tires, while the rear lift keeps the stance balanced and useful. Radius arm drop brackets and track-bar correction help maintain caster geometry and axle position so the truck remains more predictable after the ride height changes.

The 4.5 inch front and 2.5 inch rear lift combination works well for customers who want a commanding HD truck look without completely changing the vehicle's personality. It improves approach clearance, creates room for more aggressive tire packages, and helps the truck stand out visually. At the same time, the SST layout is intended to retain factory ride character better than a lift that ignores suspension geometry.

Heavy-duty trucks are often asked to carry tools, tow trailers, handle long highway miles, and reach rough jobsites. A lift for this platform needs to do more than look tall. This system supports those mixed-use demands with correction brackets and supporting hardware that help the suspension and steering stay coordinated at the new height.

The kit is designed for compatible Ram 2500 4WD applications and should be matched carefully to the correct model year, engine, suspension package, and wheel setup. Tire fitment can support up to 37 inch packages when wheel width, offset, and tire design are selected correctly. Final clearance should always be verified on the truck because aggressive wheel offsets and wide tires can change trimming needs.

Whether customers are upgrading for larger tires, towing stance, job-site clearance, hunting access, overlanding, or a stronger heavy-duty truck profile, the ReadyLIFT 4.5F / 2.5R SST Lift Kit delivers a tall SST solution with geometry-focused support. Now Available at LEER!
