Default Currie control arms

My one running the currie 4" lift? If so, what lengths did you end up at for your control arms? Looking for front and rear, uppers and lowers.

a squared + b squared= c squared
Simple math will tell you just where you should be.
a would be your stock arm length
b would be your lift height
c would be the length of the adjustable control arm to re-center the axle in the wheel well.

The lift doesn't say in the instructions? You might check to see if Currie has online instructions that have the recommended lengths.

No, the lift says to start with the stock lengths and the bars are all set to the stock length. I found another post that references the lengths for the poly performance arms, I'm going to try that and see where I end up.

I guess math is too hard?

Nope, but is it really that easy? I'm really not trying to be a smart ass, but is it linear like that?

Yes, the equation is based on a right triangle. Set your lowers to the measurements you get from the equation and adjust the uppers for caster and pinion angles. You shold come up with around 3/8" longer then the stock arms. I am basing that from memory that the front lowers are 23" long and may be off a bit.

x2 for Dirtmans use of the Pythagorean theorem. The catch is that your lift height is probably a little different than what the coils are labeled as. So, adjust accordingly.
