    Exactly what I ordered

    I had to move the spring mount because I did not want to pay the extra money but thankfully my brother in law is a welder!

    Built strong

    Added the 3.5 k axle and springs on an existing trailer that couldn't hand the weight capacity that I needed. Took me about 2 hours on my hoist to remove old axle assembly with springs and install the new axle with new springs, and tires and wheels. The products where shipped next day after I ordered. And arrived 4 days later. I highly recommend buying your trailer parts from this seller.

    Excellent Product

    Fit perfect, excellent quality, I got good customer service that answered all my questions. I do have one complaint but I'm still giving 5 stars because I know they will fix it. Lug nuts are included and bearing caps for the axle ends which is great BUT I received 4 lugs and one bearing cap because the way it was wrapped up. It does get beat up in shipping and even though you zipped tied the lugs together on each side(important to note). The zip tie broke on one side leaving 4 and was gone on the other side due to the plastic wrap getting damaged. Thread the lugs all the way on then duct tape or electrical tape, then tape the bearing cap in place where you usually put it and then wrap the plastic. I didn't take pics of mine when I got it because I just didn't think about it.
