Product Description
The BD DIESEL 1036620 High Idle Kit is a versatile idle control solution designed for Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel from 1998.5–2004 with 24-valve or 2003–2004 Common Rail (CR) engines equipped with a bell crank mounted APPS. When ambient temperatures are cold, or you’re operating accessories like a PTO, this kit lets you raise and hold engine idle for faster warm-up and steadier idle control.
This adjustable high idle kit installs easily and plugs into the factory wiring harness, with a rotating switch that lets you select idle speeds from approximate 900 up to 2100 RPM to match your needs. The included module, harness, bracket, and hardware provide a complete install package, making it ideal for cold climates, prolonged idling, and accessory use.
