Pro Speed Sensor w/ Cable - Drive Shaft

The RACEPAK Pro Speed Sensor w/ Cable - Drive Shaft is a precision electronic sensor designed for real-time vehicle speed data acquisition and telemetry logging in high-performance and motorsport applications. This compact unit reads drive shaft rotational velocity and transmits the signal via integrated cable to RACEPAK data acquisition systems, making it essential for tuners, race teams, and performance engineers who demand accurate speed measurements for lap analysis, suspension tuning, and engine calibration. The 5/16-24 inch threaded mount ensures secure installation on compatible drive shaft housings.

Built with RACEPAK's proven sensor engineering, the Pro Speed Sensor employs a magnetic pickup design that generates electrical pulses proportional to shaft rotation, delivering clean, noise-resistant signal output across a wide RPM range. The integrated cable assembly eliminates external wiring complexity and reduces potential signal degradation from electromagnetic interference—critical when mounted near high-current ignition and fuel systems. Weighing only 0.04 lbs and measuring 4.35 x 1 x 6 inches, the sensor's compact footprint allows installation in confined engine bays without interfering with existing components or accessories, while the robust construction withstands vibration, temperature cycling, and the harsh underhood environment typical of road race and autocross vehicles.

Performance drivers and data-logging technicians rely on the Pro Speed Sensor to capture wheel-speed telemetry for slip ratio analysis, differential lock-up detection, and brake bias optimization. The sensor integrates seamlessly with RACEPAK iDash and vDash display systems, enabling real-time speed readout and post-session data review. Installation requires only the 5/16-24 threaded mounting point; no external wiring, brackets, or adapters are necessary, making this a plug-and-play upgrade for vehicles already equipped with RACEPAK harnesses. Verify drive shaft boss compatibility and thread pitch before ordering to ensure proper fit.
