Description:

Restore accurate speed signals and reliable shifting performance with the genuine Eaton Fuller Speed Sensor Kit (K-4148). Engineered specifically for heavy-duty commercial truck transmissions, this OEM magnetic pickup sensor continuously monitors shaft rotation speed to send critical real-time data to your vehicle’s engine and transmission control modules. Built to resist harsh gear oil, high operating temperatures, and chassis vibration, the K-4148 kit is a direct-fit replacement that eliminates erratic speedometer readings, improper automated shifting, and related diagnostic trouble codes (DTCs).
