Jeep Leaf Spring Dimensions Reference

1955-1975 CJ-5/6 front = 36" x 1.75"
1955-1975 CJ-5/6 rear = 42" X 1.75"
1976 on CJ front = 42.5" x 2"
1976 on CJ rear = 42" 2.5"
YJ front = 42.5" x 2.5"
YJ rear = 42" x 2.5"
Late Wagoneer front = 42" x 2.5" with offset centering pin 2"
Late Wagoneer rear = 52" x 2.5" (may be 48" i forget)

All dimensions approximate based on junkyard springs. Hint, hint get extra wheelbase with the offset centering pin if changing springs. Also the spring eye on the Wagoneer (SJ) springs is HUGE on one end so add extra space in the hangers.
