Amazing Experience from Start to Finish
I could not be happier with my purchase of Trailer Parts Outlet kit to rebuild my tandem axle trailer. The order process was simple and straight forward. The parts arrived fairly quickly, and without damage.. The driver from SAIA Tsp. Co. commented that trailer parts are frequently damaged, but these parts were packaged “the best he’s ever seen”! All parts appear to be good quality. Axles from USA. Hardware pack from China.
I installed the springs, hangers/shackles, axles, wheels and tires today in about 4 hours by myself. Everything fit together perfectly! Great Job Trailer Parts Outlet!

Decent product
As long as everything shows up at the same time (one important box was lost in transit), I think this is a decent product. Haven't tested the actual capacity yet, but I'm sure that it will happen someday. I really appreciated that I could replace everything at one time and for one price. I didn't have to search for any extras.

6000 lb tandem axle kit
Kit was everything I needed to upgrade a dump trailer that had a bent axle from being overloaded.
