Thickness of Trailer Leaf Springs SP-210275 and e66SR

Question

Question:

Last week I requested specs on some springs,part # SP-210275 I received the info promptly which included a video about the springs,but a critical measurement was not included.The measurement I need is the thickness of the spring at the point of attachment. This is important as I need to mount the spring above the axle. Could you also provide me with the same specs for spring # e66SR. Thank you,

I went and grabbed a # e66SR from our warehouse and measured the thickness of the leafs of the spring where it would attach to an axle and found that it measures exactly 1 inch thick. The distance from the center of the spring eyes to the bottom of the spring measures 3 inches and this spring has the standard 1-1/2 inches of deflection.

The thickness of the leaf spring # SP-210275 is 3/4 inches. The distance from the center of the spring eyes to the bottom of the spring measures 2-3/4 inches and this spring has the standard 1-1/2 inches of deflection.
