Dominate the Road and the Trail: New FTS-X Series Suspension System Now Available for 2023+ Ford Super Duty F-250 & F-350
Whether you’re hauling heavy loads, cruising the highway, or tearing through the backcountry, the FTS-X system redefines what your Super Duty can do — combining refined daily comfort with serious off-road performance.
Purpose-built to match the legendary strength and capability of Ford’s latest Super Duty lineup, the FTS-X Suspension System delivers a dynamic upgrade for truck owners who demand more from their suspension — on every mile and every terrain.
The FTS-X adjustable radius arms directly replace the factory arms for use with lifted 2.5″, 4″ and 6″ suspensions. The arms have an adjustable lower link to eliminate binding and allow for a preferred caster profile.
Offroad the FTS-X adjustable radius arms will improve articulation over the standard fixed length Radius Arm for increased terrain traversing at all speeds. They are ready to run, pre-installed with HD Uni-balls at the OE Frame mounting location and FK rod-end mounts for the adjustable lower link.
The upper and lower tubes are constructed with 1.75″ OD x .120″ wall DOM tubing and fully welded to prevent corrosion. Radius Arms are offset and positioned inboard compared to the stock arms to allow full steering lock with a 13.50 wide tire on a 5″ backspace wheel. The FTS-X 6″ Kits are designed to accommodate up to a 40″ tire.
Fabtech’s Radius Arms have been proven for over 30 years in consumer, commercial and military applications.
