Determining The Correct Replacement Leaf Springs For Tandem Axle Trailer W/ Square Axles

Question

Question:

I have a 2006 Venture VBT-3700 tandem trailer with 2inch square, 3,500 lb. axles. I measured the leaf spring at 26.5inch center to center of the eyes, but this doesnt seem to be a standard length - possibly the springs stretched? Would you be able to provide the correct replacement leaf springs, shackle straps, hangers and triangle equalizer for a full replacement? is there a kit offered for a full replacement instead of individual parts? Thank you!

I would be happy to help you find the correct replacement suspension components for your trailer, but you will need to take a few measurements first.

Starting with the leaf springs, you will need to make sure that the tires on the side of the trailer you are working on is off the ground with the trailer supported by the frame as the leaf springs will stretch when the tires are on the ground and weight is applied.

If your 26-1/2" measurement was with the tires off the ground the closest option is the # e27SR which is for 4,500 lbs axles and is 26" long which would work as a replacement as it is not uncommon for a spring to stretch 1/2" over time. A Even though this spring is slightly higher rated it will still work perfectly on your trailer.

Moving on to the rest of the suspension, there are kits like the Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double-Eye Springs # K71-448-00 which include new equalizers, shackle straps, but you would need to measure the distance between the horizontal mounting holes in your current equalizers, and the distance on center of the two holes in your shackle straps. The # K71-448-00 has 6" equalizers and 2-1/4" shackle straps as shown in the included diagrams.

If you are wanting to remove your current hangers and start from scratch you can use the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs - 2-1/2" Front/Rear, 5-7/16" Center # APT3HD which includes the equalizers, shackle straps, bolts, and hangers. You will need four of the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 25-1/8" Long # e54SR and two of the U bolt kit # CE23103 for your 2" square axle.

I included videos of the products mentioned for you to take a look at.
