If you're rocking a 2005-2020 Ford F250 or F350, or even a 2008-2019 Ford F450 or F550, listen up. Fabtech's Radius Arms are a solid upgrade for your Super Duty, especially if you’ve lifted it between 4 and 8 inches. These arms are built tough, with a tubular design that not only adds some serious strength but also gives your truck that aggressive look you want when hitting the trails.
What’s cool about these arms is that they replace your factory ones directly, so installation is straightforward. They come with an extra degree of caster built right in, plus easy adjustment alignment cams that give you a total of 2 degrees more than stock. This is a game changer for taller lifts—think 6” or 8” setups—because it really helps with highway tracking. You want your rig to handle well at speed, and these arms deliver.
The construction is solid too, made from 1.75” OD x .120” wall DOM tubing that’s fully welded to keep rust at bay. Plus, there’s a dimple die side plate that adds rigidity without piling on the weight. And if you’re worried about tire clearance, these arms are positioned inboard, allowing for full steering lock even with a 13.50 wide tire on a 5” backspace wheel. No more worrying about rubbing when you turn!
One of the standout features here is the open design. This means the powder coat covers the entire arm, which is way better than those boxed arms that have gaps and can trap moisture, leading to rust issues down the line. Fabtech's been doing this for over 15 years across consumer, commercial, and even military applications, so you know these Radius Arms have been put to the test. If you want the best for your Super Duty, look no further.
