Is There a Replacement Spindle For a Dexter D44, 4400LB Trailer Axle?

Question:

Hello - I cant find an exact replacement spindle for Dexter D44 4400lb axles. The 3500lb one looks similar in the picture and I know some of the parts are shared between 3500 and 4400. Is the 3500lb spindle compatible with D44 4400lb? If not, do you have a suggestion for the D44 4400lb application? Thank you.

My recommendation is to replace your axle with a 5,200lb like # e55SR as the 4,400lb spindle is so uncommon they are not readily available. This will give you stronger components to lessen the chance of you having to replace a spindle in the future. If you can provide me with the dimensions for your axle I can verify the correct replacement for your D44 axle.

The #84 E-Z Lube Spindle # TRU74FR while similar has a narrower diameter of 1-1/16" for the outer bearing where a 4,400lb uses 1-1/4". If you were to use this you would lower your maximum capacity and need to change your hubs to work with the spindle.
