Spicer Tru-Lok Electronic Differential Locker Indicator Sensor for Jeep Wrangler JK Rubicon (2007-2018)

Fix blinking dashboard lights and restore reliable electronic locker verification on your trail rig with this genuine Spicer Tru-Lok Electronic Differential Locker Indicator Sensor. Specifically designed as a direct factory replacement for 2007–2018 Jeep Wrangler JK Rubicon models, this plug-and-play sensor reads the physical position of the internal locker collar inside your heavy-duty Dana 44 axle housing.

The locking differential sensor plays a critical role in your Rubicon's off-road system. When you flip the factory dash switch, the locker engages, and this sensor communicates that successful mechanical lock back to the vehicle’s computer—solidifying the dashboard light from blinking to solid. Over time, original plunge sensors can stick, short out from thermal cycling, or leak gear oil past their internal electrical seals, resulting in persistent dashboard errors or a total lockout of your automated traction systems. Replacing a faulty unit with a genuine Spicer OEM sensor ensures proper electronic resistance readings, exact thread-in depth, and excellent resistance to harsh gear oil additives.
