ReadyLIFT has engineered a line of suspension products made to fit the new 2011-2023 Ford Super Duty F250/F350/F450 4WD trucks. Our 66-2725 2.5" Leveling Kit provides new 2017-2022 F250 4WD truck owners the ability to install wheel and tire combinations up to 35" and keep the smooth OEM ride and drivability. NOTE: - This 2.5" kit provides a near-level stance on F250 trucks with the factory 3" rear block. Some may measure 0.5" less than true level. This ReadyLIFT Leveling Kit includes 2.5" powder-coated steel coil spring spacers, sound isolators, shock extensions and sway bar frame mount spacers designed specifically for the Super Duty platform. When it comes to leveling you get what you pay for. This great system specifically incorporates more than just front leveling. The sound isolator is installed between the spacer and spring to retain that great OEM ride and quiet sound. Shock extensions allow you to retain the use of those great riding brand-new front shocks rather than having to replace them with cheap aftermarket versions. In addition, Ford changed the front suspension on the new 2017-2023 Super Duty trucks and in order to raise the front of the truck the front sway bar frame mounts must be spaced downward. ReadyLIFT designed new sway bar mount spacers just for this reason, something you won't get with other kits. If you are looking to make your F250 4WD sit perfectly over 35" tires then this strong 2.5" Leveling kit is exactly what you need! ReadyLIFT Smart Suspension Technology is used to make this kit very user friendly to install, requiring no cutting or drilling. Like all other ReadyLIFT kits, the 66-2725 2.5" Leveling Kit is guaranteed for life against manufacturing defects. NOTE: Some trucks may require "67-2538 Track Bar Relocation Bracket" NOTE: Not compatible with TREMOR editions.
