This premium lift kit delivers a full 6 inches of front lift paired with Falcon 3.3 Fast Adjust piggyback shocks, providing an ideal combination of aggressive stance, larger tire fitment, and refined daily drivability.

Key Features:

• 6" Coil Spring Lift with four Monotube Falcon 3.3 Fast Adjust piggyback shocks for premium ride quality

• VOD (Volume Optimized Damping) — digressive linear piston for quicker ramp-up, reduced body roll, and bottom-out resistance
• Red Line High VI Shock Oil rated from -50°F to 450°F with anti-wear and lubricity agents for consistent performance across all temperatures
• Heavy-Duty Tubular Radius Arms included to correct caster angle and maintain proper suspension geometry
• Dual Falcon Steering Stabilizer included for enhanced steering control with oversized tires on solid axle applications
• Bolt-On Installation — no cutting, welding, or structural modifications required
• Supports up to 37" tall tires on 9" wide wheels with +18 offset
• Designed for diesel, rear single-wheel applications only

Important Notes:

• Trucks equipped with the "Onboard Scale" option will require the Auto-Leveling Headlight Bypass Bracket (PN: 67-23610, sold separately)
• Tremor versions will not achieve the full 6" lift over stock ride height
• Not recommended for 2WD or gas-powered trucks
• Single Cab configuration has not been validated for fitment and drivability by ReadyLIFT

The ReadyLift 43-23650 Big MAX3.3 system is the top-tier lift solution for Super Duty owners who demand superior off-road performance, premium adjustable damping, and a complete bolt-on kit with all geometry-correcting hardware included.
