               for HEAVY DUTY applications"

Are you looking for a new cruise control servo for your mechanical diesel engine?  Would you like to replace that ineffective vacuum cruise with a full electronic-mechanical cruise control? Do you have RV Cruise Control problems? Is your current RV Cruise Control Not working? Do you need a reliable Truck Cruise control? Our cruise control kits are the favorite add on cruise controls for truckers and RVers with older mechanical diesel engines. The King Controls Cruise King is a fully universal cruise control system that works with older Cat, Cummins, Detroit Diesel and other mechanical engines. The King Cruise is a heavy duty after market cruise control that is designed for working in the roughest of conditions. No other after market cruise control is made to the demanding specs of the trucking market.  Although not specifically made for gas engines, if you have an application where you need a tough cruise to last, the Cruise King can be modified to work with any mechanical engine gas or diesel.

Cruise King LLC can offer to owners of mechanical diesel engines, the cruise needed to fit your needs. We replace cruise controls that are no longer being manufactured, such as Bendix, Econocruise, Dana, and others. Our cruise control can be used on Semi-trucks, Recreational Vehicles and bus conversions. Our cruise control is relatively easy to install. It does not require air pumps or vacuum. All electronics and mechanical functions are located in one box called an actuator. This eliminates the need to install separate electronic and mechanical parts and eliminates a number of wires.

Why install a cruise?

A cruise control will do many things. Foremost, it EASES FATIGUE on the driver. By constantly monitoring road speed and making adjustments to the throttle, a cruise will hold a set point within a mile an hour, thus allowing the driver to take his attention off of maintaining speed. A cruise allows a driver to change positions while also taking his attention off his gauges and onto the road and scenery. A cruise control will PAY FOR ITSELF IN FUEL SAVINGS. Cruise King guarantees all drivers of high horsepower diesel engines a fuel savings of .2 MPG. A trucker can pay for his cruise control in less than one year. A King Cruise makes your vehicle more fuel efficient.

With all these benefits what is to stop you from investing in a cruise control today?

King Cruise Controls were origially designed for the heavy duty trucking industry. It is not uncommon to hear from truckers who have had over one million trouble-free miles with a King Cruise. One feature favored by truckers is the OPTIONAL dial control panel attached to te stick shift. This allows a driver to speed up and slow down with a touch of his fingers. Standard truck cruise includes toggle switches. Standard ON/OFF and SET/RESUME. Set doubles as coast or decelerate, resume is also used to accelerate.
