Can I Upgrade My 3,500 lb Leaf Springs To 5,000 lb Springs If The Measurements Match?  

I would be happy to help but first you will want to take some measurements of the hangers and shackle straps you currently have to determine which ones you'll need. Longer or shorter on the shackle straps and hangers will change the ride…

Hey Addison, the trailer hitch replacement leaf springs part #e44SR does not come with u-bolts. We have U-bolt kits that would work though like with the part #APUBR-9.

Hey Mack, instead of cranking all the way down to the point the bolts strip just go to the point where the lock washer flattens all the way and that will work.

We can get you the right shackle kit for your single axle trailer with a Dexter 3,500 lb axle, and you can choose from either a standard kit or an upgrade kit. Either will work, though the Upgrade Kit is going to be the best option due to the fact it…

We do have a more robust option to replace your 072-078-00 double-eye springs, which are for 4,400 lb axles and have a 2,200 lb capacity, like you mentioned. So for a higher capacity option, I do not recommend going any higher than a 5,000 lb spring.…

The 4-Leaf Double-Eye Spring for 5,000-lb Trailer Axles #e44SR you're referring to is made in the China.

I checked the manual for the Demco DA91 actuator part #DM8509612 and if the lever is pulled it can be disengaged by using a screwdriver to lift upward on the front of the flat emergency lever spring while pulling lever forward till it releases.

To bleed the brake lines with your Demco Hydraulic Brake Actuator w/ Drop and Electric Lockout #DM8750311 you'll need to complete the following steps: 1. First raise the tongue of the trailer 4" to 6". 2. Loosen or remove two 5/16”…

Thank you for purchasing from etrailer! You did a great job selecting compatible parts. When using Leaf Springs #e64SR with the #AP233 Equalizer Kit and the #H248 Hanger Kit, there should be 29-1/2" between the front and center hangers and…

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…

Dexter 4,000 lb axle leaf springs like the part #e48SR for 26 inches long or part #e57SR for 25-1/4 inch would work great with a 3,500 lb axle. There would be no issue with 1,700 lbs of weight either.

Definitely looks like the springs are being overloaded and need to be replaced. You can use higher rated leaf springs but, the higher you go the stiffer the ride will be. Since we know the weight class with your axles the next step would be to…
