Question:
I have a 2013 Lightening 4 place enclosed snowmobile trailer. Trailer weight plus allowable load = 7000. I presume I have two 3500 axles. Due to road salt everything needs replacing. Two questions: leaf spring length eye-eye loaded is 26 1/4, width is 1 3/4. Would the E54SR 25 1/8inch be the correct spring? Wheel center to center = 33 1/2inch loaded. And second, the axle very rusty measures 3 9/16inch in diameter which seems an odd size. Would CE Smith U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2inch Long U-Bolts - Zinc part CE23002 fit? Planning on installing the Curved Equalizer for 1-3/4inch Wide Double-Eye Springs - 5-3/4inch Long - 9/16inch Center Hole part TREQ104 utilizing the MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4inch Long Shackle Straps part MR46ZR.

Ole, was that 26" eye to eye measurement you took under load? If it was, then there's a good chance that the 25 1/8" springs # e54SR is the right choice because the springs will elongate over time and under load.
If that 26" was not loaded, then you're going to want to go with the 6-Leaf Double-Eye Spring for 4,500-lb Trailer Axles # e27SR instead.
That is an odd sized axle as well. There are 3" axles which are typically 5,200 lbs to 7,000 lbs, 3 1/2" axles which are 8,000 lbs, and 4" axles which are 9,000 lbs, but no 3 9/16" axles. With your axle being an odd size, the CE Smith # CE23002 is not going to work.

Hey Ole, how did things turn out with the 4-leaf springs and the axle setup on your snowmobile trailer? Did the measurements under load line up with the fit you needed? Your update could make it easier for others replacing similar suspension parts.
