ReadyLIFT 3.5" SST Lift Kit for 2017–2022 Ford F-250/F-350 Super Duty 4WD (2‑Piece Drive Shaft) — Lift to 37" Tires with OEM-Grade Ride

• Complete kit includes 4" OEM-equivalent rear blocks with integrated bump stop landings, 3.5" coil spring extensions with sound isolators, an OEM-style panhard drop bracket, front bump stops/shock extension brackets, a pair of radius arm drop brackets, and all necessary hardware.
• Supports wheel and tire combinations up to 37 inches while preserving a smooth, OEM-like ride thanks to ReadyLIFT Smart Suspension Technology.
• Designed for Ford F-250/F-350 Super Duty 4WD trucks with a two-piece drive shaft; not compatible with Tremor editions; verify your factory configuration before installation.
• Stance and height: when paired with max tire size, the body height increases by over 6 inches; note that 2020–2022 model years may sit slightly taller in the rear due to block height variations, producing a natural rake that complements body lines.
• Block limitations: lift blocks are not designed to work with aftermarket or factory air spring/load leveling kits that attach to bump stop tangs; using such systems will void all block warranties and can cause tang failure.
• Warranty: ReadyLIFT backs this kit with a lifetime warranty against manufacturing defects.
