LBZ Ultimate death grip
Hunter (Active duty/ aka everywhere) | March 27th, 2026
I’d love to give it a 5 star an if there’s a solution I don’t know about but, I’ll gladly change it there’s one available but install was a breeze and quality of the components far exceeded my expectations, very easy except for the idler arm weld in brace, that one was a little tricky to figure out and it took some YouTube to find the exact placement but once that was figured out it was very obvious where it went. The reason for not a full 5 star is when the suspension is at full droop I noticed the center link and outer tierod contacts the sway bar link. Honestly I can never see a situation where I’ll need to go full lock left or right with a crew cab long bed dually flexed out but you never know. I believe extended sway bar links might fix it? But I’m not sure nor have I seen on XDP, Kryptonite, or cognitos websites of a solution for it. I’d love to get some feedback back from kryptonite of a fix if they know of one

Ultimate front end kit
J-Mac (Illinois) | January 25th, 2026
Great kit! Easy to install, comes with instructions that were easy to follow. The parts themselves are very heavy and quality built with a lifetime warranty, yes, it’s pricy, but if you have a gm product, you know how bad their front ends can be, specially if ya run bigger tires. Well worth the money
