6.5" or 8" Lift..?

OK guys, im getting closer to being able to lift my truck, pretty sure im going with a Pro-Comp kit, I just dont know if I want to go 6.5" or 8". Id like to run 37"s ,can I squeak by with a 6.5" lift? If I go 8" am I going to have to do a bunch of mods..break lines, driveshaft lengthing, carrier bearing, etc etc...? There will be mild off road use, but the truck will mostly be a asphalt queen..lol
Thanky

With either lift you will have to upgrade the brake system. With that much lift you would want to have new driveshafts made. As far as clearing 37's the eight inch lift would probably work better with the six inch you may have some rubbing.

With a 6.5inch lift your gonna have to just as much work if you go 8 inches. For your 37's the 6.5 inch will work for sure and give you the clearance you need. I would think that a 4 inch lift will allow 37's to clear. I say this because a 2 inch lift allows 35's to clear. But if you go over 4 inches of lift be prepared to do all that work.

i agree with scott..... both will be as much work... as for the driveshaft the 8" kit comes with a carrier bearing drop kit and a driveshaft lenghtening block for the front...... if i were you just go the 8" and safe yourself the trouble of wanting to go bigger after you install the 6"....

I would worry more about what will rub when you are off road. The more lift you have the less chance you have of a tire snaggin a fender or something.

How wide of 37s 12.5 or wider? The 6.5 in lift should work just fine. I have a 4in and I could put 37 on it, but offroading in a turn, I might crunch a fender if in a sharp turn and bumps. Good luck with it.

37's and 4" lift works great, just experiment with wheel offsets...

A 6.5 you don't need breaklines. If you go to 8 you will need front and rear Ds's and breaklines. 37 12.50 22's look best on 6.5. you need to go a bit more with an 8 for it to look right. Don't forget gears. 37's require atleast 4:30 above that you will lose top end
