The spring benches fit the 3" axles perfectly. Unfortunately, I didn't mock up the entire kit before welding the benches to the axles. When we went to replace the axle and bolt it up, the u bolt plates were to narrow to allow the bolts through. They were off by half a bolt width. Decided to use the original plates, and when we stabbed the u bolts through the plates, the bolt was no more than a 1/4" longer than the plate, allowing about a 1/2 turn of the nuts, and grabbing 2-3 threads. I had to go to our local parts house and order Dorman U bolts and plates. This kit only lists the diameter of the axles. It does not mention the width of the springs it's made for, or the length of the u bolts. Check this before welding, so you can return if needed.

The kit arrived in Dexter branded boxes. Pretty easy install. Alignment holes and threaded adjusters make it easy to get everything square. Recommend a cut off wheel for getting the old u bolts off.

I installed these by my self in a dirt lot. Made sure I lifted a supported the trailer up off the ground about 12”. Pulled one tire at a time. Removed spring and moved to the underside of axel. Reassemble with new parts. Other side still mounted, kept axle from rotating and in line. Put tire back on, moved to other side and did the same thing. About 30 minutes a side to install.

This is exactly what you need to give your trailer a bit of lift. It lifted my trailer by about 5-6" (a tad more than just the axle diameter). I paid a professional to install, so cannot comment on the ease of installation.

Works great, took a little while to make sure everything is lined up evenly, but not bad

I used this kit to re-position the axles on an 8 x 20 cargo trailer. The kit worked very well, I did fully weld the spring mounts even though that is not explicitly required. I used the adjustments to get the new top mount perfectly parallel to the bottom spring mount and then welded it in place. The kit seems very well-made, I did notice that the new U bolts were 1/2” where the previous ones were 5/8” inch. I was not too worried about this though, because it appears to be a high grade you bolt and nut. And because it is made by a well respected manufacturer in Dexter. No washers are included in this kit, I inquired and was told that they were not necessary. I still decided to buy stainless steel lock washers and fender washers. I installed those after these pictures were taken.Overall, I would say the trailer was lifted about 6 inches.

The kit does the job. It was easy to follow instructions and once i did the first axle i established a system for the 2nd and got it done in about 45 mins.Installed on a double axle cargo trailer. I haven't driven it yet but right now i'm seeing about 7 inches of lift. I suspect that it will settle to about 5.5 inches once driven. Overall, exactly what i was looking for. Now my water tank and stabilizer jacks can be permanently mounted without scraping and i'll have some clearance to get to some of my favorite primitive camp sites.I docked a star because the package is horribly boxed. Somewhere along the way, a hole developed in the flimsy cardboard they packed it in, and a coupling nut and 5 nuts for the u bolts fell out. Shouldn't have to make a hardware store run halfway through an install.
