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

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!

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.

garbage product do not buy
absolutely trash product. no instructions is fine, i know how to install a torque converter. however this is another thing in general. first, everything is installed per another torque converter i have for another small engine. this belt is not straight, it is twisted under load, i had to make and add spacers to get it off the housing and it is still not lined up right (i need to add MORE spacers which i will not do, i am returning this), the clutch sits tight to the housing guard so wont spin when tightened down. the sprocket has to sit on the outside which is very dangerous having that chain out so far. overall very bad product do not buy you will get mad and very frustrated, and it will be because of this product being so poor.

Great customer service
Seems good but the belt is to small. Will not let the go kart idle, it is moving as soon as it starts.

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.
