measure from one end of the axle where the lug bolts protrude out from to the other end at the same point. This is the Hub Face.


Spring Center (SC):

Measure from the middle of the spring on one axle to the center of the other spring on the same axle.

There should be about 15" difference between the Hub Face and the Spring Center measurement. (7-1/2" each side
