## Customer Reviews

### ⭐⭐⭐⭐⭐ Absolutely
*by V***Y on June 16, 2025*

My second torque I’ve purchased for a different project worth ghe money value product shipping

### ⭐⭐⭐⭐⭐ Good price
*by M***  on May 29, 2024*

Fits my gx390 1in shaft. What little bit ive got to use it ive had no problems. More torque than the centrifugal clutch but less top end. Got some different size sprockets coming to fix that. We'll see what happens

### ⭐ The unit I received is flawed.
*by A***N on April 26, 2025*

I’m having problems with this torque converter sticking in the closed position. When it does, my child’s go cart will not stop. We have to kill the engine to stop. I hope the seller can resolve this issue.
