Just look at my truck, it's a 2WD with a 6" lift. I did go with 5" blocks for the rear vice the 2" block that the Fabtech kit comes with to prevent the rear from sagging. I have before and after shots in my gallery to give you an idea of how much lift you'd be getting.

? Will a 5" block sit the same as your 2"& 3"leaf combo. Is it a true 5". Reason i ask , been thinking about putting my 2.5"as on my truck.[ 6"lift with 5" blks]. I see you have a 2" spacer. Does your truck sit level? Any info helps, thanx

by the way nice truck

 

Mine sits pretty level. The back may be slightly higher but not much. I went with the 2' spacer just to be safe from bad cv angles. I know it's only 1/2 inch difference from the 2.5 but it made me feel a little better. On the rear i have the 2' Fabtech block with the 3' add a leaf which should be the same as the 5' block i would think.

 

WXSCPO that is the baddest 2wd on planet earth--I am smitten

 

i think silver's is better. the two inches in the front seem like a HUGE difference.
