2023-24 Ford F250/F350 4WD [Diesel]

Fabtech’s 2.5" Radius Arm lift kit has been built for the Ford Super Duty to handle the on and offroad demands of the truck enthusiast. This system is a heavy duty upgrade to the factory suspension and will provide additional strength to the vehicle. This Super Duty lift kit is perfect for the enthusiast looking to run oversized tires and wants additional wheel travel for offroad use. With the large Super Duty wheelwell openings and this quality 2.5" lift kit, you can run 35" tall tires with ease.

The heart of this high quality lift kit is Fabtech’s legendary tubular Radius Arms. The tubular structure design is the combination of our extensive offroad racing history and our desire to provide a smooth, compliant driving experience. The result is a suspension system with superior strength that can handle rugged offroad terrain and still navigate a grocery store parking lot with ease.

The redesigned Radius Arms have a new side plate and bold laser cut logo that gives them a modern aggressive look that will turn heads as you tackle the toughest offroad terrain.

Fabtech’s coil springs retain the factory load carrying capacity while providing increased suspension travel. The coil springs and associated bracketry allow for an additional inch of compression travel over stock without binding the suspension.

Sway bar drop brackets are included to reposition the front sway bar so that the link ends do not go over center at full droop and cause bind. The brake lines are relocated down on the frame with extension brackets to eliminate the possibility of overstretching the lines throughout the new travel range. Fabtech provides extension brackets rather than longer brake lines to keep the factory brake system sealed for fast and trouble-free installation.

This suspension kit utilizes the factory bump stops without extensions. This allows for more travel with the Fabtech coil springs and components.

Fabtech provides a heavy-duty 1/4" thick steel Track Bar mount. It repositions the track bar and front axle under the vehicle to the factory specifications. This provides proper tracking of the front and rear axle for excellent highway manners.

This Super Duty lift kit includes Fabtech Performance shocks. They are a twin tube shock that will provide a good highway ride with the ability to tackle offroad.

This lift kit is backed by our free 5 year 60,000 mile powertrain warranty.
