    Perfect replacement axle kit

    My 25-year-old aluminum trailer axle had rusted in half! I looked online for a replacement for the axle and after reviewing several suppliers, bought this kit from the Trailer Parts Outlet. I changed the type of suspension. The explanation and details on the web site were very helpful in ordering the correct parts. I found the parts to be as described, and the trailer is now ready for another 25 years!

    Almost perfect

    Nice chat with sales rep. Very knowledgeable and helpful.

    Everything arrived surprisingly. FedEx beat the love out of the packages.

    1 u-bolt was unusable with no threads (quality control issue). CS hasn't resolved that issue yet.

    Review isn't being left for the 3% future use coupon. Lol

    Great Product

    I went on line looking for an axle and found the measurements needed. I called them to verify I was reading everything correctly and they then they took my order. Only thing that was irritating was the brackets came with sharp edges and not painted from a seperate location. I cleaned up edges and painted them. Everything fit perfectly!

    no spring perches in kit

    the kit arrived with no spring perches for the axles. i ended up having to make some. the kit will not work without spring perches to weld to the axles. everything else was nice it came with extra dust caps, lug nuts, frame mounts, shackles, and all the other hardware.
