What Is a Cruise Control Kit?
A cruise control kit is a complete aftermarket system that allows you to add or restore automated vehicle speed control to cars, trucks, SUVs, and even motorcycles or boats that either never came equipped with cruise control from the factory or need a full system replacement. Rather than purchasing individual components piecemeal, a cruise control kit bundles everything you need — the electronic controller, throttle actuator or servo, wiring harness, switches, and mounting hardware — into a single, cohesive package designed to work together right out of the box.
Why Cruise Control Matters
Beyond the obvious comfort benefit on long highway drives, cruise control can actually improve fuel economy by maintaining a steady throttle input rather than the slight variations that occur with manual foot control. For commercial vehicle operators, fleets, and long-haul drivers, a reliable cruise control system reduces driver fatigue and can contribute to safer, more consistent operation over extended distances. Restoring or adding this functionality to an older vehicle can dramatically improve its everyday usability and resale appeal.
What to Consider When Choosing a Cruise Control Kit
- Vehicle Compatibility: Cruise control kits are not one-size-fits-all. Verify that the kit is engineered for your specific make, model, year, and engine type — including whether your vehicle has electronic throttle control (drive-by-wire) or a traditional cable-actuated throttle.
- Electronic vs. Mechanical Throttle: Drive-by-wire systems require a different type of controller than cable-throttle systems. Many modern kits are designed specifically for one or the other, so matching the kit to your throttle type is essential.
- Included Components: A quality kit should include the control module, servo or actuator, wiring harness, dash-mounted switches, and all necessary hardware. Check the contents list carefully before purchasing.
- Installation Complexity: Some kits are designed for straightforward DIY installation with detailed instructions, while others may require professional wiring or programming. Consider your comfort level with automotive electrical work.
- Stalk vs. Button Controls: Kits vary in how the driver interacts with the system — some integrate a stalk mounted on the steering column, while others use dash or steering wheel-mounted buttons.

Completing Your Cruise Control System
A cruise control kit is the heart of the system, but other components within the broader Cruise Control System category — such as switches, cables, and speed sensors — may be needed depending on your vehicle's existing wiring and hardware. Always review your vehicle's service manual or the kit's instructions to confirm exactly what is and isn't included before beginning installation.
