At ride height, what is the current compressed height of the spring? Put your tape up the shock hole and measure it that way.

2,250 is the total weight, but it does not take in to account the leverage ratio or what your unsprung weight is.

Unsprung weight on these a-arm suspensions is figured out like this:

100% weight for the following components:
Wheel
Tire
Brake caliper
Brake rotor
Bearings
Spindle

50% of the total weight for the following components:
Upper control arm
Lower control arm
Shock
Spring

Reason it is 50% for this is they are connected to the frame so the weight is shared.

So a stock front end has aprox 250lbs of unsprung weight from the weights I have of stock components.

The leverage ratio if I remember right on the front A-arm we have is right about 1.91 (looked at my old write up).

So, (2250-250)/2*1.91 = 1,910lbs. But that is the total weight the spring needs to support.

If you have a spring rated at 200lb per 1" of spring compression (spring rate), the spring will compress 9.55".. If you start with a 17" long spring uncompressed, installed hieght with all the weight on it should put it at 7.45" compressed height.
