This premium lift kit is built for those who crave the perfect mix of style, performance, and capability. With 6 inches of lift and vehicle-specific Falcon 2.1 shocks, your truck gains the clearance to conquer rugged trails, tow with confidence, or simply turn heads. Thanks to the 3-position Fast-Adjust settings, you can fine-tune the suspension for daily driving, moderate towing, or heavy-duty hauling. Whether you're tackling the backcountry or your daily commute, this suspension system ensures a smoother, more controlled ride with a better-than-factory feel.
Built Tough for Any Terrain
Engineered to withstand the harshest conditions, the ReadyLift MAX2.1 Suspension System features heavy-duty, laser-cut steel cross-members, forged torsion keys, and cast iron OE-style knuckles to maintain superior suspension geometry. The kit includes essential upgrades like differential drop brackets, CV axle spacers, and torsion bar relocation brackets to maximize ground clearance and maintain a smooth ride. At the heart of the system are Falcon 2.1 monotube dampers, which improve dynamic roll control and offer unmatched comfort on and off the road. The 6061-T6 aluminum alloy shock body resists impact and corrosion, while the smooth-honed internal surface ensures long-term performance. Everything you need for a precise, reliable installation is included”perfectly designed to meet the demands of today's heavy-duty trucks.
