With idle speed settings at 800, 1200, and 1800 RPM, you can dial it in based on your needs. It installs easily in about an hour and blends right into trucks equipped with cruise control. If you’re looking for added control, better warm-ups, and improved efficiency during idling, this is the upgrade your Duramax will thank you for.

Simple Hardware With Powerful Everyday Functionality

The BD Diesel High Idle Control Kit is designed to work seamlessly with 2001–2004 GM 6.6L Duramax LB7 trucks equipped with cruise control. It allows for multiple preset idle speeds by modifying how the ECM commands engine idle through the cruise control circuit. The result is a reliable solution for cold-weather warm-ups and applications requiring prolonged idling such as PTOs or mobile operations. Engineered for straightforward installation, the kit comes with detailed instructions and typically takes under an hour to install. It’s a plug-and-play solution that doesn’t require custom tuning or ECM reprogramming. While BD states the product is emissions compliant by design, it does not carry a CARB EO number and may be restricted in California. That said, this kit is backed by a 12-month, 24,000-mile warranty, giving you peace of mind and dependable idle control right out of the box.
