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).

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?

@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,

Hi Bruce, To lift your trailer we'll first need to check of the suspension and see if you have torsion axles or a leaf spring suspension. If you have torsion axles then I'll need to see the axle tag in order to determine what you have so I…

It is definitely not recommended to drill a hole in your pin box to add another set of rows. The height of your pin box and hitch will be adjustable to an extent and then you will need to adjust the axles for further leveling. My recommendation is to…

Hi Justin; do the leaf springs run under your axle (underslung) or are they sitting on top of the axle (overslung)? If you have the underslung configuration you can use the Dexter Trailer Springs Over-Under Conversion Kit #K71-384-00 you were looking…

For your existing 15" x 5" wheels an ST205/75R15 trailer tire size will work perfectly (an ST225/75R15 like what you were looking at will be a bit too wide). Within this size I specifically recommend the Taskmaster Provider #TR20515D. It…

Hey Ronnie, to pick out trailer leaf spring replacements we need to know the axle capacity and the length of the current springs. It looks like we have confirmed that your 2018 Forest River Greywolf 29TE has 3,500 lb axles though so the spring you…

Answer 9

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

Answer 10

Assuming the 25-1/4" measurement you got for the leaf springs on your 2018 Forest River Cherokee Grey Wolf 29TE was with the axle off the ground and no weight on the springs then the correct replacement spring is going to be the 4-Leaf…

Hi Jason; do you know the capacity of your Dexter axle? More arch for height isn't really a thing, and I wouldn't get longer shackles since that would throw off suspension geometry and be uneven since the front hanger stays the same. It is…

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…
