Great product, fast shipping, excellent communication, definitely recommend these guys!! We painted the square tube/king pin tube red and installed it. Works great, but there is not much of it to see in the pic. Take my word, well built & very heavy duty!!

I ordered this product and received it 3 days later, I took about 1 hour to remove the gooseneck tube and install this one and get the height set for towing, removed it once again and painted it due to it being bare metal. So far this seems to be a quality product.

It is as advertised. Heavy built. Great construction. Welds are burned in properly. I built a bumper pull to 5th wheel conversion for our camper and it worked great. I highly recommend.

Perfect for the job if you’re switching from the regular gooseneck hookup to a semi truck fifth wheel set up. Shipping was accurate & I love my adapter! Very easy to attach & real neat finish to paint it whatever color you would like to.
