• What is the Difference Between Double Eye Leaf Springs and Slipper Leaf Springs

The part # SP-124275 that you referenced will be the correct fit if your current leaf springs are 26 inches long from the center of the attachments points (usually known as eye-center-to-eye-center). You might also still be needing a U-Bolt...

• Are there Bolt-On Hangers for Trailer Leaf Spring Suspension
  
• We do have a couple of bolt-on spring hangers # CE14017G and # CE14016G but they are designed for slipper springs and not double-eye springs like # SP-124275. Its not likely that professional welder would charge that much. You might be able to find one locally via an iron workers union near you. For u-bolts for your 1-1/2 inch square axle you can use # SP01-120 for 2 u-bolts and 4 nuts. For a u-bolt plate you can use # 115983. For a hanger kit you could use # APS1. Now what you could...

• 3,500 lb Axle, Leaf Spring, Wheel and Tire, Hanger Kit and U-Bolt Kit Recommendation for a Trailer
  
• The Dexter Trailer Axle w/ Electric Brakes # 35545E-ST-EZ-89 that you referenced is a 3,500 lb axle so you will need to use springs with the same capacity. For that I would recommend the 3-Leaf Double-Eye Spring # SP-220275 that you also referenced. For a single axle hanger kit you would want the Single-Axle Trailer Hanger Kit # APS1. For a wheel and tire combo that you could run all around your trailer you could get the Karrier ST205/75R15 Radial Trailer Tire with 15" Galvanized Wheel...

• Are Bushings for Trailer Suspension Spring Hangers Required
  
• Bushings do not always have to be used. Springs typically have bushings or they will use wet bolts depending on which part of the suspension system it is but not always. The bushings limit the wear on the suspension components. There are just different designs. Kits # APS2 and # APS5 use the same 7/8 inch hangers and it is those hangers that come with the bushings. I have included a link to our help article on double-eye trailer suspension for you.

• Trailer Leaf Spring Hanger Spacing Measurements for Single-Axle Trailer Hanger Kit APS1
  
• The measurements given on the hanger kits including # APS1 are a guide only. The actual measurements will vary and to get the suspension set up correctly you would first mock up all the parts without permanently installing them. Then once the parts are in the proper positions they can be permanently installed. Basically the charts and measurements given on the hangers kits are good starting points but will not work for every situation.

• Can a Coleman Fleetwood Pop Up be Converted From Slipper Spring to Double Eye
  
• If you wanted to convert your slipper spring suspension to double-eye suspension you certainly could. It would be just a matter of changing springs and hangers.

• How To Convert A Torsion Axle To An Axle-Less Or Straight Axle System
  
• I do have a few options available for you however, we currently do not sell torsion axles. You have two options to consider for your trailer, the Timbren axle-less suspension and the Dexter straight axles. As you have a gross trailer weight (GTW) of 3,000 lbs. I recommend using a 3,500 lb setup. The Timbren System will provide you with a much easier method for converting from torsion springs in addition to containing fewer components. I recommend the Timbren Axle-Less Trailer Suspension...

• Leaf Springs, Hanger Kit, and U-Bolts for a 2 Inch Square Trailer Axle
  
• Since you do not know the capacity of the trailer axle then you can't go by the capacity of the springs. If the axle is rated for 2,000 pounds and the springs for a 3,500 pound axle then you would still be limited to 2,000 pounds. If you have the inner and outer bearing numbers then that will help to determine what the likely axle capacity is. Since you want to replace the hangers as well as the springs then it doesn't matter which springs you choose. If the axle does end up having...

• Leaf Springs and Hanger Kit for 2,000 Pound Dexter Axle
  
• You could mount springs to the top of Dexter axle # 20545I-ST-60-15 but you would have to weld on new spring seats # TRSS175. The springs seats that come with the axle are welded to the bottom. You can't flip the axle over because then the natural bow in the axle would be facing the wrong way, the tires would stick out at the bottoms, and the capacity would be diminished. The taller a trailer is the more susceptible to sway it becomes because the center of gravity is higher. Just something...
