Hello all, I'm looking to buy a 12inch for my 08 lmm sb, what is a better lift between these two? It is my first lift as well, as diesel? I need some help, if anyone got suggestions lets her them, oh yeah thinking about getting 22inch kmc revolver (matte black) on 37x13.5x22 toyo m/t. have about 5 grand saved so far, i Know i'm going to need more as being this is an expensive ass hobby ...help would be appreciated!!! Nick ?

well id do cognito waaaaaay before bulletproof. Bulletproof is full of problems from what i have heard and im sure someone with the xperience will chime in to tell why. If you set the truck at 12" i think you really hate the 37s as they will look super small. id do a 39-40 at that height otherwise you might want to drop down to a 7-9 inch if you want to stick with 37s

thanks for the input, yeah I was thinking about leaving it at 10 inches, because 40 inch tires are really expensive on 22 inch wheels!

I have the 7-9 cognito set at 8, and it needs 37's. I would imagine the 10 with less than 38's would look like my truck does with the 35's.

imo..... I wouldn't go that big with the IFS... if your gonna go that big go straight axle... it will pay dividends in tire wear for sure! let alone all the other BS problems with lifted IFS!

I have CST 9-11" set at 9 and 37's are about right... if it was bigger, a bigger tire would be a must.... and bigger tires equals more unspring weight..... and I know for me I have to replace the front hubs often enough that I could have paid for a dana 60 already!

check out mudslut's truck!! can't tell me that thing isn't badass!!!

cognito. tires start to get very expensive past 35s. also you will wear out front end parts faster. just things to think about. good luck with you decision. definately post pictures afterward.
