Question:

I currently have a custom triple axle trailer that I want to replace all 3 axles with new ones. The current measurement is 80inch HF and 68inch SC and rated at 6K. If replace with part #8327826, can I weld on new spring seats at 68inch without messing up the integrity of the axle? Also, any issues with having a wider stance by 3inch on each side? This is a custom boat trailer. I want to either weld on new spring seats at 68inch on the axle OR relocate the the hangers to 71-1/2inch on the frame. Welding on new spring seats seems to be the easier route. I can relocate the spring hangers as there is enough room under the I-beam frame, but i would have to reinforce the frame at the mounting location as the new location would be under the I-beam flange instead of the dead center. This seems like a longer term solution, especially when purchasing new axles, but more work up front and more required time that I currently do not have. Also, my current setup as 4-Leaf springs at 26. Is there any issue moving up to 6-Leaf springs rated at 6K measuring 26? Thank you!

You can weld on new spring seats on your axle without compromising the integrity. So if you went with the part # 8327826 you could install the new seats with part # TRSS300 which would be easier than moving the brackets on the trailer frame. The extra width of the wheels being pushed out would not be an issue either.

Going to a spring with more leaves would not be an issue either. We have the part # e94SR which is a 6 leaf 6k axle spring that is 26 inches long as well.

The previous answer addressed moving the spring seats in a few inches on an axle, what about moving them from ~77” to 46” on center to fit a trailer that is the same overall width, but with the heavy I beam frame rails closer together than what a typical rectangular tubing frame trailer has? Or do I need to go to axles with a heavier tube if I want the springs on 46” centers? Thanks, Greg

@GregM That's way too close together. The the spring seats normally can't be that far from the end of the spindles.

@JamesonC i have a dual axle trailer id like to put wider axles on. what is the maximum distance from hub face i can weld on new spring perches? this is on a 3500lb axle. my trailer has a 70in spring center and id like to put part number e45SR, 95in hub face axles on it. so that would be a 12.5in distance from hub face to spring perch, is that at all possible wile keeping at least most of the axles strength? thanks. John.
