TIRE/WHEEL SIZING GUIDE

  • ReadyLIFT Suspension proudly announces our all-new 3.5″ lift kit engineered specifically for the all-new 2023-2024 Ford F250/F350 Super Duty trucks. The new 3.5″ lift kits allow for wheel and tire combinations up to 37″ while keeping the smooth OEM Super Duty ride, drivability, and off-road performance. These kits are for the customer looking to create a capable truck with weekday drivability. This complete lift kit includes 5″ tall OEM-style rear blocks with integrated bump stop landings, 3.5″ coil spring extensions with sound isolators, an OEM-style track bar drop bracket, front bump stops, shock extension brackets, a pair of the all-new first-to-market radius arm drop brackets, and all the necessary hardware. 


    The bolt-on SST lift kit is simple to install without frame modifications. Maintain OE components and ride quality while gaining the confidence to venture out into the wild. The 3.5” SST lift kit is the cleanest way to run a 37-inch tire and get the most ride for your money. Optimized when paired with 37-inch tires, the ReadyLIFT SST lift kit features suspension components purposely tuned and designed to work with your truck. The 3.5-inch lift provides additional ground clearance, suspension travel, and a rugged stance while delivering robust performance on rough roads and a smooth ride for extended highway miles. 

  • Recommended tire size: 37" - 12.5"

    Recommended wheel: 17" and up x 9" wide, +18 offset / 6" backspacing (minor trimming of the front valance may be necessary)

    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.
