Hey there, truck enthusiasts! If you???re looking to beef up the suspension on your 2005-2024 F250 or F350, let me tell you about the Death Grip Radius Arm Kit. This isn???t just another upgrade; it???s built tough and ready to handle whatever you throw at it. With fully boxed and hand-welded construction, it grips your front axle like a vice, ensuring everything stays solid even on the roughest terrain.

One of the standout features of this radius arm is the tire clearance pocket. This little gem allows you to fit a whopping 37" x 13.5" tire on a stock 20" rim with 5.5" backspacing. So, if you???ve been dreaming of those beefy tires, this kit has got you covered without needing to worry about rubbing or clearance issues.

Now, let???s talk alignment. We all know how important it is to keep everything in line, especially when you???re off-roading. The Death Grip kit comes with a unique Hexagon Caster Eccentric that lets you make fixed 2?? adjustments in five different positions. This means whether you???re sitting at 0" or cranked up to 6", you can dial in your caster exactly where you want it. Plus, you won???t have to stress about losing those adjustments over time, even if you hit a few bumps along the way. That hex shape locks everything in place, so you can focus on the drive, not the alignment.

What???s in the box?
  • Durable Powdercoat Black Finish
  • Grade 10.9 Hardware for maximum strength
  • Laser Cut Mirror Finish Stainless Logo???because who doesn???t love a little bling?
  • Precision CAD Engineering for a perfect fit
  • Unique fixed position Caster Eccentric for easy adjustments
  • Direct bolt-on installation, no fussing around
  • Made right here in the USA

  • Ford F-250/F-350 Super Duty 4X4 2005-2022
  • Ford F-450/F-550 Super Duty 4X4 2005-2022

In short, if you want to take your Super Duty to the next level, the KRFDRD1 Kryptonite Death Grip Radius Arm Kit is a solid choice. It???s tough, reliable, and designed with the serious off-roader in mind.
