3.5" SST2.1 Suspension System - Ford F-150 4WD 2021-2024

ReadyLIFT now offers a new premium 3.5" SST2.1 series lift kit for the 2021-2024 Ford F-150 4WD! The 62-21440 SST2.1 Lift Kit provides a great lift solution to achieve a mild yet aggressive lifted stance while maintaining important factory ride and handling characteristics. The new 3.5” lift kit incorporates our all-new Falcon 2.1 series front replacement strut and rear shock system that delivers an incredible ride quality and opens the wheel wells up to increased wheel and tire sizes with the 3.5” front and a 2.5” rear lift over the stock ride height.

The Falcon 2.1 system pairs front monotube struts with rear adjustable piggyback shocks. SST 2.1 allows adjustment to the suspension – select a tune for daily, sport, or work duties with Falcon 2.1 Sport Tow/Haul Shocks. The easy-to-use 3-position Fast-Adjust settings include Sport/daily, Moderate Tow/Haul, and Heavy Tow/Haul.  Falcon Performance Shocks improve performance and comfort regardless of the terrain. The versatility of these systems makes them ideal for daily driving, off-road excursions, and tow/haul duties. To complement the advanced Falcon strut/shock architecture, our engineers also developed upgraded DOM tube steel upper control arms with corrected ball joint angles for greater strength and articulation, complete with (4) alignment cam plates. The ReadyLIFT 3.5" SST2.1 Kit is exclusively engineered for the new 2021-2024 Ford F-150 4WD pickups. The maximum size tire/wheel fitment for use with this kit (without trimming) is a 295/60R20 on a 9” wide and +18 offset wheel.

35x11.50 or 295/60-20 Max tire size on a 9" wide wheel with +18 offset

35"x12.5" wheel 20"x9" with 0 offset Some minor trimming may be necessary depending on the tire design.

Factory 20x8.5 +44 offset wheels can be used with tires that are narrower than 11.5"

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
