Premium Suspension Upgrade. The ReadyLIFT 4-Inch SST 2.1 Premium Suspension Lift Kit with Control Arms and Falcon 2.1 Shocks greatly enhances your truck’s capability and appearance by providing adjustable suspension modes for sport, moderate tow/haul, and heavy tow/haul. Engineered for both off-road performance and on-road comfort, it allows drivers to customize their ride for varying conditions without compromising handling or factory suspension characteristics. This system is ideal for those seeking improved ground clearance and tire fitment while maintaining driving stability.
Durable Construction and Materials. The suspension kit features heavy-duty DOM tubular steel upper control arms with high-angle proprietary ball joints, ensuring superior articulation and longevity. Components are designed with a no-cut installation, preserving your truck’s original suspension tuning, and include Falcon 2.1 shock absorbers which provide a balance of comfort and precision handling. High-quality materials and finishes ensure long-lasting strength and resistance to wear.
Installation Experience. Installation typically takes about 6 hours and does not require cutting, drilling, or welding due to the no-cut design. The kit includes components that fit precisely, making installation moderately complex and suitable for individuals with mechanical experience or professional installation assistance.
Application. This kit is designed specifically for 2019-2024 Sierra 1500 models without Adaptive Ride Control and Super Cruise technology, excluding the AT4 trim. Compatibility excludes 2019 Classic body LD, Limited, or Super Cruise variants and vehicles equipped with mono-leaf rear springs, which require a separate kit.
