Readylift 6" Lift Suspension System Falcon 3.3

ReadyLIFT is proudly expands our industry-leading Super Duty lineup with the release of the all-new 6” MAX3.3 Coil Spring Suspension System for 2023–2026 Ford F250/F350 diesel 4WD trucks.

This high-performance kit is engineered for customers demanding premium ride quality, larger tire fitment, and daily drivability — all backed by ReadyLIFT's reputation as the go-to brand for Ford truck lifts.

Key Features:
Dual Falcon Steering Stabilizer – Adds control and confidence with oversized tires on solid axles.
Heavy-Duty Tubular Radius Arms – Built to correct suspension geometry and withstand Super Duty abuse.
Bolt-on Installation – No cutting, welding, or fabrication required.
37” Tire Fitment – On 9” wide wheels with +18 offset.
Falcon 3.3 Fast Adjust Piggyback Shocks – Terrain-tuned dampers with on-the-fly compression adjustability (Soft, Custom, Firm) and 8-position micro dial.

o 3.3 Fast Adjust Dampers offer a wide range of adjustability for specific terrain and/or handling characteristics with two separate knobs to tune to your preference.
o 3-Position Fast Adjust Knob for Soft, Custom, and Firm Compression. Soft mode allows a partial bypass of the main piston for a softer ride
o 8-Position Micro Adjust Dial offers refined damping adjustments
o Reservoir design increases nitrogen to oil ratio for consistent damping over wide temperature ranges.
o Hard Anodized Large Bore 6061-T6 Aluminum Shock Body for impact and corrosion resistance as well as increased oil volume for consistent performance.
o VOD (Volume Optimized Damping) features a digressive linear piston for quicker ramp-up for reduced body roll and an overall increase in damping to reduce bottom out when pushed to the limit.
o Red Line high VI shock oil for consistent performance across all temperatures from -50F to 450F with anti-wear and lubricity agents.
