Lo-inch is the free length of the spring
(unloaded)
Di-inch is the inside diameter , every spring on this page is
2.50 inches inside diameter.
C-lbs./inch is the actual spring rate, expressed in pounds
per linear inch.
Sc-inch is how many inches the spring can be compressed
before it coil binds.
Fc-lbs is how many pounds of force it takes to compress the
spring until it coil binds.
WT-lbs is actually how much the spring weighs, and has
nothing to do with the stiffness.
