Hanger Spacing Recommendation for Tandem Axle with Leaf Springs SP-222275

Question

Question:

How would I determine hanger spacing using product SP-222275 on a tandem axle. And what height difference would a 5-7/16” center hanger have vs a 4-1/4” center hanger with 2-1/2” front and rear hangers?

Expert Reply:

The hanger spacing you'd need to use is 29-1/8 inches with the leaf spring part # SP-222275 with a tandem hanger kit like part # APT3.

The height difference would be an inch.
