Rick,

10 inch spring 240 per inch rate, compressed 2.5 inches = 600 lbs preload.


8 inch spring 300 per inch rate, compressed 2.0 inches = 600 lbs preload.

But the next inch is:

10 inch, 240 lb. 3.5 inch compressed = 840 rate.

8 inch, 300 lb. 3 inch compressed = 900 rate.

Therefore, depending on your motion ratio, 300 might not be enough to stop the bottoming out.
