Questions & Answers about Replacement Trailer Springs:

2015-08-26A shopper asked: if a spring capacity is 1,000 lbs and there are two springs on the trailer, left and right sides, can they hold a 2,000 lb boat ? thanks

Leaf springs typically have the part # stamped on the strap that holds the leafs together at one end of the shorter leafs, or it is painted on the concave side of the springs. The part number can then be used to determine the capacity of the springs. Generally springs with any age on them will be very hard to get a part number off of. You would then need to go by the axle capacity to determine the spring capacity, which would be 1/2 of the axle capacity. If you have a 3,500 lb capacity axle the springs should be rated for 1,750 lbs each. The axle capacity can be determined in one of 4 ways. First, most trailers have a tag that has the VIN # and axle capacities listed on it. Second, there is sometimes a tag on the axle that indicates the axle capacity. Third, the diameter of the axle can help determine its capacity in many cases, see below. Finally, the inner and outer bearing part numbers on the axle will indicate the axle capacity.
The leaf thickness, width and number of leaves has nothing to do with the capacity of the leaf spring, because the quality of steel and how it has been prepared for use as a leaf spring will affect its capacity. Some single leaf springs can carry more weight than a 5 leaf spring that seems to have 5 leafs all the same thickness as the single leaf spring.
Typical Axle Diameters Based on Axle Capacity:
1,000-lb - 2,000-lb Axles: 1-1/2inch - 1-3/4inch diameter
3,500-lb Axles: 2-3/8inch diameter - Can have a 3-1/2inch diameter, but rarely
6,000-lb - 7,200-lb Axles: 3inch diameter
8,000-lb Axles: 3-1/2inch diameter
9,000-lb Axles: 4inch diameter
10,000-lb Or more axles: 5inch diameter
