Default Rear shock adjustment

Sent my Penske doubles out for an oil change last week. I marked the spring location and removed the springs before I boxed them up and sent them away. They came back today and the marks I put on the threads were wiped off. Now what? Where do I start?

should go back to where they need to be when you get your ride height reset. how did you determine there location when you set them before? i'm sure when penske rebuilds shocks (which is basically what you had done) they clean them so you can't really expect a mark you left on the shock to be there when they were returned.

You are absolutely right about the mark I put on them, I should have measured them and recorded the number. The car was new to me last year and set up when I got it.

actually you should have measured ride height and adjust the shocks to get the ride height where it needs to be. now your gonna be guessing a bit.

The shock should have a recommended installed length . Then adjust ride height from there?

i agree with kris^^^^ call penske and ask where they want the shock to be set measuerd from center of bolt to center of bolt. adjust your spring platforms to get the desired distance, if its a four link car your gonna wanna scale it again to make sure your corner weights are close .i guess that goes for a ladder bar car aswell .

If you have any pre-load in the car it's going to throw your corner weights off, so don't try to balance your weights unless you take any pre-load out of it first. Make everything neutral then begin your chassis setup. If you don't do this, and you jack things around so the weights are all equal, it will be all out of whack.
