Overview

The ICON Vehicle Dynamics Ford F-250 & F-350 Super Duty Radius Arm System is designed with adjustable caster cams for use with 2.5-3” lifts with the radius arm installed in the factory pivot, eliminating the need for caster bushings. When used in conjunction with an ICON radius arm drop bracket system, proper caster can also be maintained for 4.5” and 7" lifts, including coilover conversion systems. They feature a sealed pivot bushing that minimizes road feedback and ensures a long life and quiet operation. Additionally, their fabricated, fully boxed design ensures strength and utilizes a profile optimized for tire clearance at full steering lock, making a 37” tall tire clear without coming in contact with the radius arm.

Features & Benefits

  • Fully boxed design
  • Built in caster adjustment for optimized return to center
  • Replaceable sealed pivot bushing provides maintenance free operation
  • CNC machined and laser cut steel components
  • Semi-gloss black powder coat finish
  • Ability to have a 5.5” backspace wheel with 37” tires without contact with the arm at steering lock

Night and Day Difference.
I only had one negative with my F-350 and that was the harshness of the ride. These shocks fixed my complaint and are amazing on the truck. Made it almost feel like an F-150 going down the highway. Highly recommend!

Really Great Shock For the 1st Gen Tacoma
These Icon Aluminum Series 2.0 w/ Reservoir shocks really impressed me. I paired these Icons with the Icon 3 leaf progressive AAL with my stock leaf pack, which gives me 1.5 inch lift in the rear. They have been an amazing upgrade from Bilstein 5100's. The quality of the machining and finish is great. And, the shipping was super fast from Shock Surplus.

What a great lift and shock combination! Works very well on and off road. The further articulation of the billet UCA’s adds tremendous freedoms on the trail. And an excellent purchasing experience as their staff answers questions with knowledge and experience. Not the cheapest system, just one of the best!

The Expert's Opinion

"We've been big fans of Icon's total suspension approach since running the CDCV kit on our Tacoma back in 2017. Icon regularly provides the most travel in their shocks and suspension systems when compared to competitors, giving more lift height, or more usable travel."
