Well guys i am about to begin a new truck build. I have built an 05 F150 and a 2000 7.3L from the ground up.....now I am beginning a project on a 2011 6.7 (hopefully theres a chance I go with a 6.4L but pushing for a 6.7 just getting my plans in line). A flatbed from Diesel Power Gear will be going on this truck too as well as 40" Tires.
I am debating between 3 different suspensions because of price and options.
A) McGaughey's 8" $3100~
- 4-Link
- Add-A-Leaf
B) Pro Comp 8" Stage 2 $2280~
- MX-6R Shocks on all 4 corners
- Not 4-Linked
- Add-A-Leaf
- Best Price by alot
C) BDS 4 Link $3800~
- 4-Linked
- Fox 2.0 Shocks
- Dual Steering Stabalizer
- Full Leaf Pack Replacement and no blocks

Obviously the BDS is the best package, but I am not sure if I need/want to spend the extra $700-$1600. I will be wheeling this when I can. I ran a Rize Industries on the F150 and full leaf packs front and rear on the F350 no blocks and didnt mind the rough ride. I know the value of a good suspension but I would like some opinions.

 

The shop I use has installed many Carli suspension systems. Universally,the owners have very pleased.
The parts are high quality,deliver the ride and fit perfectly.
These have been 3" systems.

 

Carli is nice but they are only 3 inch systems and I'm doing 8"

 

Most of the guys I know have the BDS and they no problem with it though this kit is really expensive.
