If your leaf springs are the lowest rated component on your trailer then if you were to use leaf springs with a higher weight capacity, like part # e54SR, it would increase your total weight capacity. However, it sounds like you have a 2,000 lb axle weight rating. In that case upgrading your leaf springs to a higher weight capacity would not increase the weight capacity of your trailer.

Since you are always limited by the least rated component you will want to find that component and upgrade it. If the trailer itself is only rated for 2,000 lbs then you will not be able to safely carry any more weight than 2,000 lbs per the manufacturer's rating.

If you let me know what the least rated component is on your trailer I can make some recommendations for you.

Answer 5

If you are wanting to go to higher capacity leaf springs I would advise against it. The problem is that since the trailer axle is rated for 3,500 pounds you won't gain any additional capacity by switching to higher capacity springs. What it will…

I can certainly point you in the right direction. Unfortunately we do not have access to Dexter's serial number database, and I cannot recommend springs based off of axle specs. If only it were so easy right? The best way to go about replacing…

The typical springs for the AL-KO 4,400 axles are one of two lengths. If you have the 25-1/4 inch length, then you will want the 4-Leaf Double-Eye Spring for 5,000-lb Trailer Axles #e28SR, but if you have the 26 inch springs, you will want the 6-Leaf…

Answer 10

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.…

Answer 11

Though I do tend to warn people about the ride getting stiffer when upping the capacity of their leaf springs, you are correct in that you will technically never be fully "unloaded". I do have to mention that this could still happen, but…

Answer 12

I have two options for you to raise your trailer and gain more clearance between the fender and tire. The most cost effective option would be to flip the axles with a Dexter Trailer Springs Over-Under Kit part #K71-384-00 or part #K71-385-00. That…
