8" lift on an 05 CCSB

[duc796]

Hey guys, I am looking into doing an 8" lift and 37s on my truck and I am wondering if you go that big do you want to do anything with the driveline or is it just fine being such a long wheel based truck. I posted this under the exterior discussion too but it doesnt get too much attention over there. Any input would be great! Thanks!

Bump, im interested also, Since i should be doing my lift very very soon, either 8 or 10 inches.

I have a 03 F250 with a 8" fabtech lift and 40x15.5x22s. One issue you will run into is rubbing. Wheel spacers with fix some of the issues. You may still have some rubbing in the area near the bottom back of the wheel well and on the bottom of the bumper at the wheel well. And yes I'm running 40s but I have freinds with 37s and they have had the same problems.

Now for the drive train...I recommend you start using heavy duty U joints, you should not have any drive shaft angle problems. When you put the lift on check/replace your bearings. Take the truck to a shop that works on lifted trucks to get the alignment done, it's different on lifted trucks as the toe needs to be set different to compensate for wider larger tires. Under braking the wider larger tires will settle back causing steering problems while braking. Brakes....when its time to replace your pads next time, get rotors and pads for lifted trucks its a world of difference.

Good luck and enjoy.

Good deal, thanks for the info. With the lift that you put on did you go with a 4 link conversion? The kit I am looking at is a 4 link conversion. From what I hear the ride is a lot better with the 4 link and getting rid of the factory set up.

Thanks for the info! How much did those big meats kill your fuel mileage? I have 35's on now I wouldnt think it would be much different with another 2" of tire but who knows.

i just installed a 8" lift in my drivway a couple weeks ago. Things I ran into was having to fabricate some drpo brackets for my break lines up front, as well as a 3" extension for the bracket that the abs sensor mounts to on the passenger side.

I have some axel wrap now, nothing too major though.
I didn't notice it at the time, but my upper balljonts were blown on both sides. I wish I had taken care of those while I had all the tools out and the front end apart.

the 8" lift coils up front are a sweet ride. soo much better than the factory ones.

enjoy the lift! The extra height really sets it apart

HawaiiBake, what kit did you go with? I am looking at the rough country 8" 4 link kit that one goes for about 1500 with shocks.

Ive had 5 lifted superduties, and I can tell ya if you really tow, you will want to skip the hassle and just have custom one piece driveline built. The two peice will have to be spaced down and aligned and will always still vibrate on takeoff due the design of the rubber donut (carrier bearing) mounting point between the two. One piece is the only way to totally eliminate all issues.

I dont tow too much with mine every once in a while but nothing crazy like that monster 5th wheel in your sig. Is the vibration only when you are towing or all the time with that kind of lift?

I just put an 8" lift w/37's on my 05' with a 4 link. The ride isn't much worse that stock... Jetjock15 is absolutely correct about the drive shaft, every time I take off from a stop, my truck vibrates for a second then smooths out... A 1 piece drive shaft is in my near future...You will definitely have to put the spacers to drop the carrier bearing... but it will still vibrate... The only time my tires rub is when I go up or down a curb too fast...
