New-Line Heat Sink

Maximize the efficiency of your cooling system without adding unnecessary weight to your kart.

The New-Line D300 Heat Sink (300 mm length) is the ideal solution for all drivers and teams looking to optimize engine operating temperatures, especially on the hottest days or during the most intense racing sessions.

Designed by New-Line Racing, a world leader in kart cooling systems, this finned tube is directly integrated into the water circuit as a junction between radiator hoses.

Why choose the New-Line Heat Sink?

• Optimized Cooling: The enlarged inner diameter slows down the water flow speed. This allows the liquid to stay longer inside the heat sink, maximizing heat exchange.
• Maximum Dissipation: High-quality external aluminum fins utilize racing airflow to drastically reduce water temperature before it re-enters the engine.
• Lightweight and Compact: Weighing only 0.615 kg and with an outer diameter of 50 mm, it is the perfect alternative to an additional radiator, avoiding extra bulk and weight on the chassis.
• Racing Quality: Entirely made from solid aluminum with precision finishes, it ensures maximum resistance to vibrations and track stresses.
