Got a high-performance RC model with a 40mm outer diameter motor that gets toasty? This INTEGY cooling kit is built just for that. It's a twin 40x40mm high-speed fan setup pre-attached to a billet-machined aluminum alloy heatsink mount. The fans are wired up and ready to go, so installation is pretty straightforward. The heatsink part comes in a bunch of anodized colors – black, green, gunmetal, orange, purple, red, or silver – so you can match your ride's style. It clamps onto most 40mm OD brushed or brushless motor cans and helps pull heat away, keeping your motor temps down and performance up. Overheating can kill power and efficiency, so this is a smart add-on for serious hobbyists who push their models hard on the track or trail. Made in the USA with quality materials, it's brand new in original packaging. Whether you're racing buggies, trucks, or just want your motor to last longer, this cooling combo is a go-to upgrade. Fans spin fast to move air, and the aluminum sink dissipates heat quickly. Easy to DIY install with basic tools. Keep your RC running cool and reliable!
