Kryptonite Death Grip Radius Arm Kit 05-25 Ford SuperDuty

Okay, so why would you want to upgrade your factory stamped steel radius arms to these Death Grip Radius Arms? First, what exactly is a radius arm and what does it do? The radius arms on your truck are responsible for tying the front axle to the frame and allow it to cycle relatively vertically with a slight amount of swing due to the triangulation from the pivot point. To some degree, they aid in side to side movement of the axle, as well. Besides looking extremely impressive, they offer many improvements to the performance of your suspension, as well. This radius arm was designed and built for maximum durability, high tire clearance capability, and an industry leading range of caster alignment adjustability. By having this type of caster adjustment, you can ensure you eliminate any of the "floating" feeling these trucks are notorious for, even in stock ride height. Fully boxed and hand welded construction ensures a Death Grip hold on your front axle. 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. This means a nice, tucked in stance without the radius arm rub you'd get with stock arms, or even many aftermarket arms. Kryptonite kept alignment adjustability in mind with the design of this arm. Utilizing their exclusive Hexagon Caster Eccentric allows you to make fixed 2 degree 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 losing your adjustments over time or with rough driving. The Hex shape of this Caster Eccentric will lock your alignment adjustment into place.
