deciding on lift. gonna go with TF, and trying to decide if i want a 4" or 3" and should i opt to buy the "full-flex arm" package as well, are they even necessary?

im going to run 35" tires and LOD front and rear bumper. im debating going to 5.38's due to me living in Colorado and the altitude seems to kill me a bit more so im going to pass on the 5.31's

so questions are... Full flex arm...yes or no and why?
is my plan for 5.38's gonna be a smart move or am i asking too much of my gas mileage to gain performance?

I would go with the 4" because your going to loss a little when you install your bumpers, any where from 1/2 inch to 1 inch due to the weight of the bumper. On the gears go 5.38's all the way. Believe it or not you will get better fuel mileage because it want down shift as much with 5.38's as it will with 5.13's. I wanted 5.38's but don't have a rubi and don't have enough $ for a d44 front axle. About the full-flex arm's, I don't know the benefits of them but I would get them because it just sounds cool. Remember (5.38) thats the magic number. Good luck with your project.

Decide on a tire size, then choose the lift. If you do a little browsing, (here, or right on the TeraFlex website) you'll find that the TF 3" coils give 4-5 inches of lift, and the TF 4" coils are in the 5-6" range - depending on model and added weight, of course..

TF 2.5" or 3" coils if you stay with 35's
TF 4" coils if you plan on 37's


If you don't go for the flex arms, what is your plan for adjusting the caster?
When you blow your driveshafts from the added height, how will you set the angles on the new shafts?

You might take a step back and browse through the FAQ's, then move on to some of the other TF lift threads and gearing threads and ...
