Leaf Spring Recommend for Tandem Boat Trailer w Springs 26 inches Long and Axle 2 inch Diameter

Question:

Im trying to order new leaf springs but I cant locate the axle weight rating. My trailer is a tandem axle boat trailer with 2inch axles. The current leaf springs are 26inch double eye, three leaf springs. Can you please help me to determine the correct axle weight and springs.

If you can find the plate near the coupler of the trailer you should see the axle capacities listed there. Another option is that you can measure the diameter of the axles to get a good idea what the capacities would be.

Typical Axle Diameters Based on Axle Capacity
- 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter
- 3,500-lb Axles: 2-3/8 inch diameter
- 6,000-lb - 7,200-lb Axles: 3 inch diameter
- 8,000-lb Axles: 3-1/2 inch diameter
- 9,000-lb Axles: 4 inch diameter
- 10,000-lb Or more axles: 5 inch diameter

Since you said your axles are 2 inch it most likely is around a 3,500 lb axle, but you might want to remeasure to be sure.

For a 3,500 lb 3-leaf spring that measures 25-1/4 inches you would want the part # e57SR. You should note that springs have a tendency to stretch over time and that this spring be 25-1/4 inches would most likely be the exact length of your current springs when they were new.
