Check my math

[bigramman03]

For those of you who don't know me or my truck, I have a 2003 Dodge Ram 1500 4x2. I currently have a Rough Country 6 inch (turned out to be 6.5)susupension lift and a 3 inch body lift on my truck giving me a total of 9.5 inches of lift. That will clear 37s good. Now I'm still not satisfied and I'm gonna go higher. I'm gonna put a 2.5 inch coil spacer on top of the spring. Now by my math (6.5+3+2.5) that gives me 12 inches of lift. Full Throttle sells a 12 inch lift for the 02+ 1500 4x2s and it clears 39.5s so my set-up should do the job as well right?

Here's some links if you want to see pictures of the Full Throttle 12 inch kit on an '03 1500 4x2 with 39.5s.

that could possibly work, if the 2.5" spacer fits and it does not overextend what you have

also remember you have to align the vehicle was all is said and done
