Measuring for shock question

What is the process of measuring to find the correct length of shock in a custom application? Do I need to have the weight in the car as it is to be driven? ie; full tank of gas,p***engers, vehicle ride height? Thanks for the help. later shawn

 

the shock should have a bit more travel than the suspension does, so it won't bottom out at full down travel (such as going over a serious bump).

You can use the shock to limit how far up the car goes such as when you jack it up and the wheel comes off the ground.

Ride height isn't a concern...what happens at the end of travel is what you have to worry about.

 

Your ***umtions are correct. Once you get your ride height dimensions, allow appx. 3'' of travel for compression, and 2'' of travel for extension. These dimensions are changeable depending on the angle of the shock on the car. The more angle, the less travel required, and the softer the shock will act.

 

I agree...about 60% of a shock's travel left for compression and 40% for rebound, from installed "ride height".
