how much wider does the stance widen compared to the cognito?

I believe 1.5" versus 3/4" per side. I would not run that kit on your truck, I have seen too many problems with it.

i was just wondering because know around here has ever heard really of any of the west coast lifts,only thing advertised here is fabtech, pro comp, rancho, and super lift. anyways i was wondering if i ran the cognito at 8 like the fabtech would they be the same height?

also do you have to replace the rear driveshaft on cognito 10-12? and since you have one can you still go through drive throughs without scrapping the roof?

You will only have to replace the front one, or just have it lengthened and rebalanced, that is what I do. I can still fit through most drive throughs. Stay away from the corporate lift shops, because they are the ones that are going to push you into a lift like procomp, fabtech, etc. pm me if you want a price, and I can get you a good deal on the kit, even with shipping.

yeah its not the price i have a buddy with a offroad shop and i get everything at cost, i just want to know a cognito 10-12 with some 38's is the way i want to go. I mean i want to get the truck all banks powered out with some 4.56's, but i would like my truck to look like yours, its a nice truck!

i would like the 10-12 with 38's but i might have to go with the 7-9 with 37's.

Either way cognito makes some of the best stuff on the market. Make sure you post pics when it is done.

I hear what you are saying about the fabtech stuff. Here on the east coast or at least in the north east I have gotten alot of odd looks for Cognito. Its basically the lift I would choose just looking at the parts and reading the posts though. It seems the 4 shops that I have in my area didnt like them and were very pro the fabtech..now they did have alot of Fords that are around and in the pics with the fabtech and that could be a great kit for the fords.

i have a fabtech lift right now on my truck and its been a good lift cause ive done alot of offroading and never had anything to worry cause my tcase has a skid plate but ive read some other post where theyve never had a problem of them hiting with a cognito lift. but than again there alot more sand on the west coast than here so i dont know if i can have it exposed like that.

another question...do the idler and pitman arms fit with any kind of lift or just cognito?

also would 3.73 gears be to high of a ratio for 37's cause alot of people on this site have 4.56's with 38's and bigger.

you need a sig. dude we have no idea what kind,year,make truck you have and that makes a huge difference in answering all these questions.

steer clear of the fabtech 8 in my opinion. and yes a cognito at 8 will be just as high if not higher and your cv and steering angles will be much better

the problem with drive thru's such as a bank teller is the width more than the height. you WILL NOT fit the wide way.and you won't be able to reach anything.fast food drive thru's are no problem.except everybody in the place wants to ask you questions about your truck for 5 minutes.

some people go with the west coast look and run the front higher. its called "cali style". i do not like that look and have 10" springs and 2" blocks for about 1" of rake. also known as "texas rake".

if you have a 2 piece rear driveshaft you'll be fine. i did nothing but space mine down with the cognito spacer. the front one you'll need to buy a new one,which cognito sells, or have yours worked on

D/M, you only had your front shaft lengthened? because mine would'nt bend enough to even get close to the diff. i had to get the dual cv shaft from cognito to get it to work.

my questions arnt for my truck i have now. im planning on buying a dmax whenever i get this all figured out. im just wanting to do all the figuring so i no how much money i need, cause all of this depends on how much i sell my truck for and how much i can take out of the bank..

also thanks for the tip for the wideness i might just go with a 7-9 set at like 8 with 37's cause this truck still needs to be able to go through the bank!

does anyone still recommend regearing with 37's or are they ok?

inferno you think your truck has room for 37's without cranking, im more than likely going to get a winch bumper so the the front wont be a problem and the back part of the fender can be trimmed?? or does the amp step bars connect close to the front fender?

and also nice truck! very cool the way everything matches.

what are you buying? a new body style truck or a 07 classic or older? crew cab? long bed?

still won't fit thru bank teller lines. and you will not be able to reach down to get to the drawer,etc.

from a 2004 to 2005 chevy 2500 hd 4x4 duramax crew cab short bed, what im planning on getting this winter. i need my truck to be able to still go through drive throughs and stuff like that and so i think the 7-9 is more what im looking for cause i want to clear 37's maybe 38's i would love it to like this truck http://memimage.cardomain.net/member_images/5/web/2465000-2465999/2465176_11_full.jpg http://memimage.cardomain.net/member_images/5/web/2465000-2465999/2465176_15_full.jpg
i like the way cst does there lift too though and i like that the front tcase is protect but i read on the site that those lifts arnt as good... but that truck is one of my favorites

also ive noticed that most of the trucks on the norcal and socal websites have there trucks torsioned up so much so they dont have to cut the fender....heck i would rather have a little fender trim and have a bad ride, the truck in the pictures i think they did the same and didnt trim just torsioned

B-rad, yes my front shaft is just lengthened and rebalanced, hooks up fine, and still engages in 4 wheel drive.

If you get the new bumper, then you can 37s. Amp steps wont be in the way at all.

Thank you.

im thinking of the buckstop outback....anyone got any feedback from that bumper?? also is banks one of the best tunners/exhuast/intake on the market or are they some out there that blow it away?

If you want maximum power look at efi live. It is a custom tuned programmer, it is a little bit pricey, but produces sick power.

i would run 37's and put 4.56 gears in it the cognito is a good lift i not sure how far my rcd sticks the tires out but i run 37's and i can go to any bank i need to the problem i run into the most is my rack is taller then my cab so my cab may clear things but the rack won't. if you do any type of hauling i would go with the bigger rear springs that way you don't get the nose sticking up
