Adding Lift to 3,500 lb Trailer Axle


Sounds like a stupid idea. Embarressed to even ask. Can I flip this axel to get a lift? Dexter Trailer Axle Beam with 4 E-Z Lube Spindles - 95 Long - 3,500 lbs Item # 7685269

It's not a stupid question, it's a perfectly logical one but you should not flip the Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindles # 7685269 to get rise as this was not the intended design as it is an underslung axle with spring seats that are intended to be on the underside of the axle.

There is a way to add lift to a 3,500 lb axle such as the straight Dexter Trailer Axle Beam # 7359765. What you would use is called an over/under kit, which is commonly referred to as flipping the axle but is really just moving your trailer's leaf springs to the top of your axle, as you can see in the accompanying photo.

For a 2-3/8" round axle such as the Dexter Trailer Axle Beam # 7359765 you would need Dexter Trailer Springs Over-Under Conversion Kit # K71-384-00.

These kits lift your trailer approximately the same amount as your axle's diameter plus the height of the leaf spring pack (please keep in mind this conversion kit is for use with double-eye springs only).

how wide of axle should i use with a trailer that is 84 inch wide 77691

Reply from Chris R.

The exact length depends a bit on the tire size you're planning on using. Also, does the 84" width you mentioned include the fenders? 63241

@ChrisR I have an Echo Trailer EE-9-13 frame I got from a junk yard with no axle. What size axle does this call for? It is a 2011. Tire is ST175/80D. Looks like it use to have a 2000lb axle according to sticker but wouldn't mind putting a 3500lb axle on. Thanks, 75196

@Ryan How wide is the trailer frame center to center? 75220

@JonG Looks as if the frame measures 80 inches. Online it looks as if the measurements from hub to hub were around 72 inches and spring to spring 60 inches. What would you recommend 3500lb axle for carrying a polaris ranger? Thanks, 75232

Reply from Jon G.

@Ryan Thanks for the measurements! If your trailer frame measures 80" wide on center then you're going to need an axle that has an 80" spring center measurement. This is because leaf spring hangers are mounted to the trailer frame. For your application you'll probably need something like the Dexter Axle # 7359765 which has a 95" hub face measurement and an 80" spring center measurement. Is the 72" and 60" what your previous axle measured? 75237

@JonG Perhaps I misunderstood measuring the frame from center to center. The entire trailer is 80 inches wide. Previous axle - from what I read through online threads measured 72/60. I have also called Echo but have not heard back. I found a link to my trailer, although mine is a 2011. Measurements appear same. Thanks, 75238

@Ryan Okay that makes more sense. In that case the 2.2K Dexter Axle # T20BTR-EZ-7258 would be closer to what you're looking for. This has a 72" hub-face measurement and a 58" spring-center measurement so you will want to verify the spring-center measurement on your trailer just to be on the safe side of things. If you go to the product page you can see some pictures of this installed to give you a good idea of where you'll need to measure. 75242
