Hi Gordon; it looks like you figured this out since you ordered the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long # TRU62FR. As long as your axle capacity is 3,500 lbs and you measured your existing leaf springs at 27" these will work as a replacement.

Any trips coming up with your boat before the end of summer?

Answer 12

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…
