Product Description
The BD DIESEL 1036627 Duramax High Idle Kit is the perfect performance upgrade for Chevy and GMC Duramax diesel trucks, engineered to provide adjustable high idle speeds for faster engine warm-ups, extended idling, and PTO or high-load accessory applications on 2008–2019 6.6L Duramax engines. This high idle kit lets you bypass the factory auto-engine-off function and maintain elevated idle speeds from a simple dash mounted switch.
This kit includes a high idle control module, wiring harness, dash switch bracket, and hardware for an easy install that plugs into your factory wiring. The rotating switch allows selectable idle speeds including 900, 1200, 1500, 1800, and 2100 RPM — ideal for cold climates, frequent stops, ancillary equipment power, or any application where keeping your Duramax warm and responsive matters most.

FAQ
What does the high idle kit do?
It enables adjustable elevated idle speeds, boosting warm-up performance, supporting remote starters, and helping with PTO or accessory loads.
Is installation difficult?
The kit installs in most trucks in about 1–1.5 hours, mounting a dash switch and connecting to the existing throttle wiring with supplied harness and hardware.
Will this interfere with my factory ECM or tuning?
No — it adjusts idle without ECM tuning or cutting factory wires, making it easier to uninstall or transfer to another truck.
