Description

Engineered Exclusively for Air Ride Models: Rough Country's 3.5" Bolt-On Lift Kit is precision-built exclusively for Chevy Tahoe models equipped with Adaptive Air Ride Suspension. This premium lift solution delivers aggressive styling, trail-ready performance, and factory-ride compatibility, all in one easy-to-install package. Forged Strength Where It Matters: Built tough with Forged Aluminum Upper Control Arms, this kit offers superior strength, impact resistance, and long-lasting durability. Designed with OE-style rubber bushings and pre-installed high-articulation POM ball joints, the control arms maintain optimal geometry while allowing smoother suspension travel and greater range of motion, on and off the pavement. Lifted Clearance, Level Stance: Gain the confidence to tackle rugged terrain with increased ground clearance and rear lift strut spacers that allow clearance for up to 305/55R20 tires. The result is a bold, level stance that improves both form and function while eliminating factory rake. Perfect Fit, Full Compatibility: This kit is purpose-built to maintain full functionality of your factory Adaptive Air Ride system, ensuring seamless integration with all ride height modes. Each component is laser-cut with CAD precision for a professional fit and clean finish that aligns with OE quality standards. Straightforward, Bolt-On Install: Installation is 100% bolt-on and requires only basic tools and minimal trimming. With pre-installed components and no need for complex modifications, you can install with confidence, right from your own garage. Peace of Mind Included: Rough Country backs this kit with a Limited Lifetime Replacement Guarantee, ensuring your suspension is ready for whatever comes next.
