High Idle Kit for Cummins and Duramax Applications

Cold mornings, remote starts, and long idle times can be tough on your diesel. That’s where the BD Diesel High Idle Kit comes in, an easy upgrade that gives you control over your truck’s idle speed for faster warm-ups, smoother PTO operation, and better performance during extended idling. Whether you’re running a Cummins-powered Ram from 2007 to 2022 or a 2020–2022 GM 6.6L Duramax, this kit is built to make your truck more functional and comfortable in real-world conditions. One of the most useful features is how it allows you to raise idle RPM in set increments, 900, 1200, 1500, 1800, or 2100 RPM, depending on your needs. That means you can warm up your engine faster on cold starts, maintain consistent power when using a power take-off (PTO), or keep voltage stable if you're running auxiliary equipment at idle. It’s also ideal for trucks equipped with remote start systems or for drivers who idle for long periods in cold weather.

Puts You In Control

The system bypasses factory auto engine shutoff functions, so your truck will stay running when you need it to. Installation is straightforward and typically takes under two hours with basic tools. Once installed, it’s simple to activate and adjust, giving you greater control with no fuss. This high idle kit is fully compatible with 2007–2022 Ram 2500/3500 Cummins, 2008–2022 Ram 4500/5500 Cummins, and 2020–2022 GM 2500/3500 Duramax trucks. It’s a great solution for fleet use, work trucks, or any diesel owner who wants more control over engine warm-up and idle functionality.
