Heavy Duty: Great heavy duty kit. Very clean steel brackets for easy welding. All bear steel for painting any color you want. Good price for the complete kit!!!

Good Quality: Just upgraded from some homemade (not by myself) axles on the trailer project I bought years ago since those original ones went u-shaped, and so I decided to put proper slipper springs on since those came with the replacement axles I had bought used as replacements. Needed the shackles though, so I went with these. I wish they had included some paperwork on the proper spacing with different spring types, but after some extensive research online I was able to get that info. Good fit and finish and they work well lightly loaded. Haven’t loaded them heavy yet but so far they work well. Will update if I have any issues once I run this setup through its paces. I’m sure I’ll be dragging something home soon, so won’t be long before I know.

kit was incomplete: I received only 1 nut out of 6. had to use old ones with lock-tite
Beefy Leafspring: Just installed this product on my 6×10 utility and I’m impressed with the size difference from the original stock 3000lbs leaf springs. Be sure to buy longer U-Bolts to fit around this bad boy.
good: all good

Marginal quality spring steel: I used this as an emergency spare spring for my 40′ 5th wheel toy hauler. This spring has slightly better build quality than the one I replaced (see the better clamp on the photo), with normal load it still flattened out noticeably after 3 months of use.
Fix tired and leaning trailer suspension: Replaced the leaf springs on my 2020 Jayco travel trailer. AT 37,000 miles they were a little flattened and uneven. Distinct list to the right. Replacement was not difficult, you need a level work site, a good floor jack, stands and hand tools. Took me about four hours. Recommend new bolts in case the anti-rotation splines are worn. That was still easier than dealing with a warranty claim. My dealer is 80 miles away.
Traler kit: On time delivery box well fit my traler easy to install so happy
