Replaced the springs on my HWH jacks. Found the best prices at:

Get the model number of your jacks first, I found that my front jacks were different from the rear. Here is a chart on spring sizes.

A note of caution. Per the chart, and upon investigation, I found the recommended spring for my rear jacks was 18" long, however, the distance between the mounting brackets on my jacks when fully retracted was only 16". If I went with the recommended springs, my jacks would never fully retract. I went with a HWH spring rated the same that was 14" long.
Here is the data on mine.
