Rostra Precision Controls

About Rostra Precision Controls

Rostra Precision Controls has spent nearly 150 years earning its place as one of the most trusted names in precision automotive manufacturing. Cruise control kits may be what the brand is best known for in the aftermarket world, but Rostra's product portfolio spans far beyond a single category — covering transmission electronics, switches, sensors, and an extensive range of vehicle comfort and safety accessories.

Rostra is an ISO 9001 and TS 16949 certified company, a standard that reflects its deep roots as an OEM supplier to some of the world's largest automotive manufacturers. That same engineering discipline flows directly into every aftermarket part the company produces, giving professional rebuilders and serious DIYers access to components built to meet or exceed original factory specifications.

Cruise Control Systems: A Category Leader

Rostra is widely recognized as North America's largest aftermarket cruise control supplier. Their cruise control kits are engineered to work with an exceptionally wide range of vehicles — from classic cars with mechanical throttle linkages to modern drive-by-wire platforms. Key features found across their kits include set speed, coast, resume, and a fine-tuned tap-up/tap-down function for one-mile-per-hour speed adjustments, giving drivers precise highway speed management.

Complementing those kits, Rostra also offers standalone cruise control modules for direct replacement applications, as well as a broad selection of cruise control switches — including disengagement switches, stalk-mounted buttons, and brake-pedal-actuated safety switches that ensure the system deactivates correctly when the driver applies the brakes.

Transmission Electronics & Powertrain Controls

Rostra's powertrain division is a respected force in transmission repair. The company manufactures core drivetrain electronics — including automatic transmission shifter solenoids, sensors, wire harnesses, and modulators — that govern fluid flow, gear changes, and pressure regulation inside modern automatic transmissions. These parts are engineered and validated against OEM benchmarks, making them a go-to choice for transmission shops and rebuilders nationwide.

Switches & Electrical Components

Rostra's heritage in precision electrical manufacturing also extends to a variety of vehicle switches. Their turn signal switches and related steering-column electrical components reflect the same commitment to quality and fitment accuracy found across the rest of the Rostra lineup, offering reliable replacements for a wide range of domestic and import applications.
