Springs and weights inside are probably cheap or incorrectly assembled. The plate is good thick steel however ### ⭐⭐⭐ Not a fit for counterclockwise rotation engines, but not hard to modify *by I***K on Reviewed in the United States on March 23, 2020* Doesn't seem as poor quality, but most small engines rotate counterclockwise, and thisT converter has positively wound spring on the driven pulley. You Will have to take apart tge driven pulley and modify the red spring reversing it to become negatively wound.The red spring that cones with T converter, them reds are all weak springs. You could stretch the spring, and also bend forward like, the last 1.5 inch length of the spring ends. All that adds to the spring stiffness. Also use different hole to wind the spring, so you can achieve more stiffness that way too. All in all this product seems ok, but, if you have counterclockwise rotation engine, it will make you do some work, and figure things.Yellow negatively wound spring from comet is best solution ### ⭐⭐⭐⭐⭐ not a one brand fits all kind of unit good and heavy duty *by G***Y on Reviewed in the United States on January 2, 2022* nice and heavy duty kinda pricy but you get what you pay for --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/444326401-blast-led-predator-420cc-go-kart-torque-converter-kit-40](https://www.desertcart.kr/products/444326401-blast-led-predator-420cc-go-kart-torque-converter-kit-40) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-07-11*
