BD Diesel High Idle Control Kit

The BD Diesel High Idle Control Kit (also called a high idle kit or diesel governor controller) lets you raise the engine idle speed of your Duramax diesel truck from inside the cab. Cold-weather warm-ups go faster, and you get a steady elevated idle for work and auxiliary use.

Key Features:

• In-cab adjustable switch for selecting the high idle speed
• Faster engine warm-ups on cold mornings
• Suited to remote starters, PTO operation and extended idling
• Dash-mounted switch that plugs in under the dash, so installation is quick and easy
• Designed and built by BD Diesel Performance for GM Duramax diesel applications

Whether you need to warm the engine up faster, run a PTO-driven accessory or idle for long periods, this kit gives you a convenient, reliable way to manage idle speed. Each kit is made for its specific Duramax engine generation, so choose the variant that matches your application.
