Question:

Replacing my slipper springs on boat trailer. I have a new 3500 pound axle. My current springs are 3 leaf 1 3/4 in wide, flat slipper. Off the trailer the eye to end is 28 inches,arch height is about 3 1/4 or so. Hanger distance on trailer is 27 inches straight line measure from eye to center is 13 1/2 in, curved measure is 14 1/2. Looking for at least or close to 3000 lb total on springs. Suggestions? Thanks, Chuck

Hey Chuck, thanks for all of the dimensions you mentioned from your current springs. Based on that the best replacement option we have would be the part # e89SR which is for a 3,700 lb axle, is 1-3/4 inches wide, and overall is 30 inches. Your hanger distance of 27 inches would be perfect for this as well.
