Worth every penny.
Ricky (Utah) | August 18th, 2025
Good fit, extreme improvement in ride quality (with new kryptonite lower ball joints at the same time) over stock arms and ball joints, I’m actually blown away. With a bad gearbox it still corrected a lot of the slop in my steering and even helped with some of the bounce from my less than optimal shocks. (The guy I bought this from didn’t take care of it). Kryptonite cam/caster adjusters didn’t work with my lift but I just jacked up the front end and used a pry bar to line everything up on the machine. Everything fell right into place and now my truck is able to be perfectly aligned. I’m a mechanic for a living and inspect a lot of vehicles. When it comes to suspension, I’ll never recommend anything other than these products on big trucks again. Absolute game changer.

Great fitment, good looking!

Easy install (3rd set of uppers in a year). Definitely improved ride quality, Before with a torsion key lift it drove like a log, noticeably improved the loud thumps / stiff ride. Worth the money since these are about $200 more than regular uppers.
