6-Inch 4-LINK Lift Kit

The Superlift K231F-SUP is a comprehensive 6-inch lift kit engineered for 2005-2007 Ford Super Duty F-250 and F-350 4WD models, specifically benefiting diesel engines. This kit features precision-engineered, heavy-duty tubular 4-LINK arms equipped with Superlift's Reflex bushings. These bushings offer superior vibration dampening, flexibility, and durability, while the 4-LINK design optimizes suspension control and tire wear by limiting caster change throughout the suspension cycle. The front of the vehicle receives new, diesel-specific rate coil springs, and a new track bar relocation bracket is included to ensure proper steering geometry and track bar phasing. This kit includes front and rear Fox Performance Series 2.0 IFP shocks, providing enhanced damping and control. All necessary installation hardware is included, with no major cutting, welding, or drilling required for most models. Additional notes for installation: If your vehicle is equipped with a 2-piece rear drive shaft, a carrier bearing spacer (Part # 9669) is required. For Super Duty models equipped with 1-7/8" blocks and top overloads, Part #11874 must be purchased separately. This Superlift kit is proudly assembled in Louisiana and made in the USA with global materials. It is backed by Superlift's limited lifetime warranty against defects in materials or workmanship.
