Warm up your engine faster on cold mornings with BD Diesel's High Idle Kit. Quick and easy to install, the High Idle switch mounts on the dashboard. Newer model year trucks use a plug-in module with advanced electronic controls, along with a rotating switch for adjustable high idle speeds from 900 rpm to 2100 rpm. Early model years utilize a toggle or rotary switch that wire taps under the dash to select different RPM ranges. Great to use for remote starters, PTOs and extended idling applications.
