I have a 2003 dodge ram quad cab 4x4 with a Fabtech 6 in lift kit on it. I want to take it even higher. I was wondereing since it has blocks in the rear could you put add-a-leaves in the back and put a leveling kit torsion keys for the front to get about 2 more inches of lift. I have 35 in nitto mud grapplers but i want to be able to put 37 in nitto mud grapplers on. Thanks for the help.

 

what about a body lift??

 

Im not a fan of the body lifts. I hate how you can see a gap in the rear and then the hitch and exhaust sit lower and it just looks funny I think. I had a body lift on my last truck, and I dont think I will do it again.

 

Gap guards.

 

At 6" of suspension lift, you are already well beyond the angle that your IFS CV joints are recommended to operate at. Just adding the extra weight and rotational force of 37's now is asking for trouble, you put any more stress on that front end you are going to destroy the CV joints, especially if your not a pavement queen and actually take your truck off road.
The body lift is your only real solution, as it does not increase the angle of the CV axles. A more popular and far stronger setup for 37's on your very weak IFS front end would have been to put a 4" suspension kit on in combination with a 3" body lift. The gap guards and front/rear bumper brackets would take care of any cosmetic issues.
