Expert Reply:

I saw you were looking at double eye leaf springs so we will assume that is what you have. In regards to leaf spring hanger spacing, the most common for a triple axle trailer is 29-1/2" first to second (center to center), 34" second to third (center to center), and 29-1/2" third to last (center to center). Therefore, it would be best if you would place the leaf spring hangers accordingly.

Once the leaf spring hangers are in the above positions then you have a few options based on axle capacity which I have attached for you below:

3,500 Lb Axles:
Leaf Spring - part # e57SR (6)
Equalizer/Shackle Strap/Bolts - part # APTT3

5,000 Lb Axles:
Leaf Spring - part # e28SR (6)
Equalizer/Shackle Strap/Bolts - part # APTT3

6,000 Lb Axles
Leaf Springs - part # e34SR (6)
Equalizer/Shackle Strap/Bolts - part # APTT3

7,000 Lb Axles
Leaf Springs- part # e64SR (6)
Equalizer/Shackle Strap/Bolts - part # APTT3

The Triple-Axle Trailer Hanger Kit for Double-Eye Springs part # APTT3 is more cost effective than piecing together the equalizers, shackle straps, and eye bolts which is why I recommend this route.
