The product didn’t work for me. But I would give it a chance.
The belt just spun and ripped apart. Bent the clutch. Extremely disappointed. I contacted them but they didn’t respond. Update- the company did contact me. They asked what happened and wanted to investigate my situation so they could make changes so this doesn’t happen to others. I really respect that and speaks volume. They made it right. Why I changed my rating.

Good quality go kart part!!
This is great! So far so good!! The quality looks very good and I’m very exited to put a lot of use on it. Got it for a replacement part for my go kart and the quality looks like it’s gonna last for a while!

Bad quality
DO NOT BUY. Back plate is not even square so pulleys will not line up. Save your money

keyway
the drive hub keyway very low you can see the machining markings where they cut it 3 different heights should be one to fit a 1/4 inch keyway slot scared it would spin on crank shaft but overall, very solid unit

Needs work to be able to use
The holes had to be redrilled as the belt was so tight the bike wouldn’t idle. Bad fitment, but so far holding up good

High quality torque
These are high quality torque converters. Central belt life is crucial. The life of the belt depends on how hard you send it. A high quality spare belt with any torque converter is recommended.

Belt meh but good enough
Would prefer it came with a few more belts of higher quality as its rather squeaky when at idle but other then that it zooms quite fast
