2021-2026 F-150 6" MAX3.3 Suspension System w/ Falcon 3.3 Adj Shocks (42-21641)

Description

The ReadyLIFT 6-inch MAX3.3 Suspension System takes the 2021-2026 Ford F-150 4WD from capable to unstoppable. Built around Falcon 3.3 Fast Adjust remote reservoir dampers, it pairs a full 6 inches of lift with genuinely tunable ride quality, so the same truck can commute quietly on Monday, tow to camp on Friday, and get pushed hard on Saturday. Heavy-duty fabricated steel crossmembers, lifted knuckles and DOM tube steel upper control arms correct the suspension, steering and driveline geometry so factory handling manners survive the lift.

Features

• Delivers a full 6 inches of lift for serious ground clearance and a properly aggressive stance.
• Falcon 3.3 Fast Adjust dampers with two independent tuning knobs for on-road and off-road use.
• 3-position Fast Adjust Knob for Soft, Custom and Firm compression; Soft mode partially bypasses the main piston for a plusher ride.
• 8-position Micro Adjust Dial for fine damping changes between the primary settings.
• Remote reservoir design raises the nitrogen-to-oil ratio for consistent damping across a wide temperature range.
• Hard-anodized large-bore 6061-T6 aluminum shock bodies resist impact and corrosion while carrying more oil.
• VOD (Volume Optimized Damping) digressive linear piston ramps up quickly to cut body roll and resist bottoming out.
• Red Line high-VI shock oil holds performance from -50F to 450F with anti-wear and lubricity additives.
• DOM tube steel upper control arms with proprietary heavy-duty high-angle ball joints.
• Heavy-duty fabricated steel components built from 3/16" and 1/4" steel plate.
• Full-coverage differential skid plate in 3/16" steel plate.
• Fabricated steel 4" rear block with factory-style U-bolts for correct rake and a straightforward install.
• Includes HD alignment cam bolts for proper front-end alignment after the lift.

Notes

• Alignment, headlamp aim, and ADAS recalibration (if equipped) are required after installation.
