Hello John, thanks for reaching out. I an provide some rough guidelines for you, but there is not a "set in stone" hanger spacing for a 27" leaf spring and I cannot provide exact locations for anyone spring and hanger combo unfortunately. I do have a guideline for you in regards to trailer leaf spring hanger spacing on a triple axle trailer with 25-1/8" to 25-1/4" trailer leaf springs but we can't offer specific measurements as there are too many variables involved. I have included the chart for you below.

The best practice for this is to tack weld on your hangers, assemble your suspension and see how everything lines up. Then if you need to adjust the hanger spacing you can move them as needed before welding them on permanently. There may be a bit of trial and error involved, but that is the only way to nail down your hanger spacing.

Hey John, how did things go once you tack welded the hangers and tested the spacing on your triple axle trailer? Your results could really help others working through the same setup.
