Work as it should. My son flipped his go-kart and he stayed in place.

Within 1 week of installation, one of the buckles stopped latching to the central hub, rendering it useless. Luckily, I did not throw out the OEM set and reinstalled one of the old belts. This set appears to be just as crappy as the garbage that was originally installed!

We bought a Trailmaster GoKart for grandkids this Christmas and the the buckles failed on the harnesses on both sides of the kart. They will not lock into place. Was not treated poorly and will not let them ride until the harnesses are replaced. It shows to be the same harnesses that are in the picture.

I am 5’10” and 250#. These are going into a go-cart for kids and they are too big for me. I understand that it’s the go-cart manufacturer that needs to address this problem and not the seat belt maker. The seat belts themselves are great.

Perfect

I’ve got a 10yr daughter that the seat belt was to big. Safer for not to use
