alright guys got my truck fully laid out minus front subframe.

I need to know how i should set my drive line when laid out. Please keep in mind im fairly new to this all and this is my frist air build.

thanks!

dude... didn't you read the whole post? isnt' this YOUR post to begin with?

I have been reading the articles you had posted. I have some understanding about having your driveline setup at ride height but mine is being built layed out and i wont know what my ride heigh will be forsure. I'm just having some trouble understanding everything. I dont want to have to redo everything because of vibrations or issues. I am trying to undersrand everything to my best ability.

I just need to know what my last shaft section and pinion should be angled at when layed out in order to have a decent angle at ride height or What my pinion angles should be at right heigh in order for them not to be incorect when laid out or fully aired.

i know there are multiple variables when figuring this out but i cant do this by myself

and that's your problem. set it up at ride height. ride height is determined before you build anything. its a height you determine. i decided (on my truck) i wanna drive it, lets say, 4" off the ground. that's my ride height. that is the height you set your lower bars parallel with the ground. that is the height you set up your pinion angle. once you have that set, tabs for upper and lower bars tacked onto the axle tubes and frame, cycle it thru the suspension travel and check for binding. if its good, jack the axle up to where you'd be 'layed out' and make sure its level. use jack stands. that's where you want to build your bag brackets.
to find where you are layed out, know your final tire size. if you change to a larger tire in the future, take that into account. use a tape measure and find the distance from the ground to the frame, and make the bottom of the tire the same distance. like you could put a straitedge (the ground) along the bottom of your frame and it'll also be on the bottom of the tire.
did that make sense?
i guess i''m just going to say again that's why it doesn't make sense to set up your suspension 'layed out'

Digging up an old thread while searching and I think others will like to see this as well as it's full of good information for link design and placement.
Sask, did you end up using the program or not?
