Our new Death Grip Radius Arm Kit is just what you need if your looking for the ultimate suspension upgrade to your 2005-2022 F250/F350 Truck! Fully boxed and hand welded construction ensures a Death Grip hold on your front axle. This Radius arm was designed and built for maximum durability, high tire clearance capability, and an industry leading range of caster alignment adjustability. 

Built into the box welded structure of this arm is a Tire clearance pocket which will allow clearance of a 37" x 13.5" Tire on a stock 20" rim with 5.5" of backspacing.

We kept alignment adjustability in mind with the design of this arm. Utilizing our exclusive Hexagon Caster Eccentric allows you to make fixed 2° incremental changes in 5 different positions. This means that at any ride height from 0" up to 6" you'll be able to dial in Caster exactly where you need it. The best part is, no worrying about loosing your adjustments over time or with rough driving. The Hex shape of this Caster Eccentric will lock your alignment adjustment into place.
