Its the Carli 3" Pintop lift. Full Rear leaf replacement, new coils, radius arms are theirs (Much stronger), king 2.5s all 4. Rear factory airbag drop brackets (So that system works like factory).
35 Inch Nitto Ridge Grapplers
20 Inch x 8.5 Dually Rims, Fuel Cleavers, I don't know offsets, I called them and told them look I wanted and they gave me this.
I bought a 18 kit and made it work, very few mods (control arm bracket).
Eventually I will be running the carli sway bar, right now im running the stock bar and drop brackets (New frame is slightly skinnier than 18) So once that's released I will get that on there.
I also added a small 1" block in rear to get me slightly ass high ( I hate perfectly level HD trucks)
Truck drives unreal!!,
this is my 3rd 1 ton diesel, my last truck being a 13 dually, nearly identical spec to this truck, that truck got a bds 6 inch kit. The carli drives so much better they are not even in the same league.
I do a ton of towing, and this setup is like driving a escalade or better. Unreal. The rear airbags are a must, if ur truck doesn't have the factory setup add the firestones, the carli leafs are not as rigid, they have way more give to them. But its not even noticed as the bags fix that when im loaded. Ive dropped my form trailer on there, about 5k sitting directly on tongue and it sits as level as unloaded.
The most noticeable difference in ride quality is hitting a bridge at highway speed under heavy load, NO bucking, no steering torque, just coast right over it, no hard shake. The quality is above and beyond anything ive ever had or even tried on a pickup.
I could have gone with 37s also but didn't know that when I ordered everything, I have 4.10 gears and it seems good with that ratio still (For heavy towing) but 37s would add some strain on everything for sure.
What kind of hardware are you running? ( tire size, rim size, suspension)
