4" 2025-2026 Chevy Silverado 1500 - SST2.1 Lift Kit (w/Falcon 2.1 Coilovers & Shocks) by ReadyLift

The ReadyLIFT 62-35440 4” SST2.1 Lift Kit is the premium suspension upgrade engineered for Chevy Silverado 1500 owners who refuse to settle for ordinary. This system isn’t just another lift kit—it’s a complete transformation in capability, comfort, and performance. Designed around the all-new Falcon 2.1 Series front struts and rear shocks, this kit delivers ride quality and control that basic spacer lifts can’t match.

Falcon Performance Shocks redefine what’s possible in a mid-size lift system. With a 3-position Fast Adjust system—Sport, Moderate Tow/Haul, and Heavy Tow/Haul—you can instantly tune your suspension for daily driving, aggressive off-road terrain, or hauling heavy loads. Predictive handling, enhanced stability, and superior damping ensure your truck remains composed and comfortable, regardless of the environment.

This system features heavy-duty DOM tubular steel upper control arms with high-angle proprietary ball joints for increased articulation, long-term durability, and improved suspension geometry. The 4” front lift paired with 2.25” rear blocks maintains ideal rake, allowing for significantly larger tire fitments, including 295/65R20 (Chevy) and 295/55R20 (GMC & Chevy), unlocking the aggressive stance and clearance your truck deserves.

The SST2.1 system also utilizes Smart Suspension Technology, offering a no-cut design that preserves factory ride characteristics while greatly improving off-road capability. Engineered with precision components, including 6061-T6 aluminum shock bodies, induction-hardened chrome shafts, and Falcon’s advanced damping technology, this kit delivers unmatched performance, reliability, and value. For daily drivers, weekend explorers, and work-ready trucks alike, the ReadyLIFT 4” SST2.1 system elevates your driving experience with superior strength, capability, and ride comfort. This is the lift kit built for those who demand the best—on the road, off the road, and everywhere in between.
