The 7 leaf, 2 inch wide, 4,000 pound rated springs you're looking for are part # SP-285275. To install them on your triple axle trailer use the hanger kit # APTT6SE. I've linked an article to help you determine the placement of your axles. Once you have a good starting point you want to mock up the complete system before installing anything permanently. Using the # APTT6SE hanger kit your hanger spacing should be roughly: 29 inches between front and first center hanger 33-1/2 inches between center hangers 29 inches between the second center hanger and rear hanger
