About this item

  • Engineered for 42mm diameter brushless motors—including the widely used 4268 and 4274 models—this aluminum heat sink delivers intelligent thermal management for high-performance 1/8 and 1/10 scale RC vehicles from Traxxas, Arrma, and other top brands.
  • Equipped with a precision thermal sensor and a near-silent 40mm fan, it activates cooling only when motor temperature hits 45°C (113°F), conserving battery power while ensuring active protection during hard runs—so you get more drive time and fewer thermal shutdowns.
  • Powered directly from your receiver with no extra wiring or ESC modifications required, this plug-and-play design makes installation fast, clean, and hassle-free for racers, bashers, and trail builders alike.
  • Machined from high-conductivity aluminum with a secure clamp mechanism, it maintains full contact with the motor can for efficient heat transfer, lowering operating temperatures and extending the life of your motor and ESC under demanding conditions.
  • Whether you’re racing on hot pavement, bashing through dust, or crawling steep rock lines, this smart cooling system keeps your powertrain running cooler and more reliably—so you stay on the track longer and enjoy every minute behind the wheel.
