I have an '06 5.4L 2wd and i'm thinking of a 6'' suspension lift....any suggestions?? I had the Pro Comp 6'' stage 2 kit in mind...

 

That kit is fine, but the 6 inch Fabtech is a little better quality but it costs more.

 

i have the stage on with fabtech coilovers. i havent heard any bad things about the procomp stage II though. i love my lift. i mean only differeance is i have fabtech Dirt logic coilovers.

 

Fabtech w/ adjustable coilovers + steering stabilizer.

 

I have the exact same truck as you and went with the 6" Fabtech performance lift and am very happy with it. Have had it on for almost 2 years now and absolutely zero issues. You could go with the coil overs, they add a better look, but if you're truck is basically a daily driver and kept on pavement for the most part then it's just it's a lot of extra money you don't need to spend.

 

Also, look into California Super Trucks. CST lifts are very well engineered.
