Front springs and ride height
Posted: Fri Oct 15, 2010 4:18 pm
Hi,
I wonder if some of the theorists out there can help me.
The ride height on my +2 130 seems to have sagged recently as I have started grounding on split road humps that it used to clear without problem. On checking I found that the measured ride height under the front cross member had dropped by about an inch from the 6.5 inches I set it to a couple of years ago. Rear ride height under the diff shelf by the way was still spot on.
As I have Protech front dampers with adjustable spring platforms I decided to wind the ride height up.
Having moved the lower spring platforms up by 0.45 inch and done a shake down ride I find the ride height has only risen by about half an inch. I was expecting more.
My question is : Is there any linear relationship between how much I raise the spring platforms and how much the ride height increases? And was I wrong in expecting the ride height to increase by significantly more than the amount that I wound up the spring bases?
Help please!
