Review of Dexter Trailer Leaf Spring Suspension - HD Suspension Upgrade Kit Single Axle - K71-358-00 Video

Hey Jaime, yes you can replace your 25-1/4 inch 3,500 lb axle leaf springs with a 5k rated axle spring like the part #e44SR. This will increase the suspension's weight capacity and might make the ride quality a little rougher but it would fit and…

Hey Kevin thanks for your question. There is not much downside to going with the 5,000 lb springs instead of the 3,500 lb. A higher rated spring may make the ride a bit more "chunky" at times, since the spring would not flex as easily.…

The 4-Leaf Double-Eye Spring #e44SR is our closest leaf spring to the Dexter 072-078-00 which we do not carry. Each of these springs is the same 25-1/4" from eye to eye but are rated for 2,500lbs per spring versus the 2,200lbs you are needing.

The bushing on the Rear Hanger with Bushing #30-20 has a 9/16" diameter and is 1-3/4" long so you'll need to use one of the bushings in the Dexter Bronze Bushings Kit #K71-291-00 as a replacement.

The Moryde wet bolts #MR52HR use a standard 1/4"-28 thread for the zerk fittings.

The shackle bolts used between the springs and hangers do not require a specific torque rating because tightening the shackle bolts too much will squeeze the shackle straps against the leaf springs, and the whole suspension system will bind and cause…

You can upgrade the 1750 lb leaf springs to 2500 lb leaf springs. You do want to keep in mind that the ride may be a bit stiffer since you are upgrading your springs to a higher capacity. Like you mention upgrading the springs will not give you a…

In order to find the correct leaf springs for a Dexter D-40 Axle you'll need to measure their unloaded length and keep in mind as the springs age/wear, they will stretch so the replacements are likely shorter. I don't know what length springs…

We definitely have a few options available for a 3,500 pound Dexter axle. That being said, you will need to measure your current leaf springs to see which one will fit. This should be done going from the center of one eye to the center of the other…

If the leaf spring part #e57SR that you referenced matches up dimensionally to what your trailer has and has a capacity that is 400 lbs more than needed it would work just fine. Having a bit extra capacity for the leaf springs would not cause an…

In regards to measuring shackle straps, you don't need to remove them to measure accurately. If they are still installed on the trailer simply measure from the center of each bolt head, the two most common are 2-1/4" part #TRSL225 and…

When replacing shackle straps they should be the same length as the ones that were previously on your tandem axle trailer; replacing them with longer straps will result in additional play in your trailer suspension which could lead to additional wear…
