Lisle NOx & Soot Sensor Offset Socket Set 24mm & 30mm for 2014–Current Ram 3.0L EcoDiesel – 1/2" Drive, 6- & 12-Point

Lisle 12290 is a two-socket offset set made to reach and service NOx and soot sensors on 2014–current Ram 3.0L EcoDiesel V6 engines, giving technicians the clearance and engagement needed to remove and install sensors in tight spaces.

When sensor bodies sit behind wiring harnesses, brackets, or limited clearance near exhaust components, a standard socket often won’t fit. This Lisle set includes both 24mm and 30mm offset sockets built with combined 6-point and 12-point ends and a heavy-duty 1/2" drive to tackle stubborn or hard-to-reach NOx and soot sensors found in Jeep Grand Cherokee and Dodge Ram 1500 trucks with 3.0L EcoDiesel engines.

How do these offset sockets make sensor access easier?

The offset design shifts the socket axis away from obstructions so the tool can reach sensors that sit behind brackets or wiring. Each socket’s geometry reduces interference and lets a ratchet or breaker bar turn the sensor without bending connectors or unplugging components.

• 24mm and 30mm offsets fit common NOx and soot sensor hex sizes
• Offset length provides clearance past harnesses and heat shields
• 1/2" drive accepts standard ratchets and bars for leverage

What makes the 6-point and 12-point combination useful?

Each socket offers both 6-point and 12-point engagement so you can choose the best contact for the sensor hex and available swing clearance. The 6-point side reduces rounding on tight fasteners; the 12-point side allows finer ratchet positioning in cramped areas.

• 6-point side protects sensor hexes from rounding
• 12-point side enables smaller arc movement for limited swing
• Dual configuration increases versatility across different sensor heads

Will these sockets handle seized or tightly torqued sensors?

The set is built around a heavy-duty 1/2" drive to deliver the torque needed to break free stuck sensors while maintaining tool strength and durability. Use a breaker bar or impact-rated accessories where manufacturer guidelines allow.

• 1/2" drive transmits higher torque than 3/8" drive tools
• Robust construction resists deformation under load
• Suitable for use with ratchets and breaker bars for extra leverage

Which vehicles and sensor types is this set intended for?

This Lisle set is tailored for 2014–current Ram 3.0L EcoDiesel V6 engines commonly found in Jeep Grand Cherokee and Dodge Ram 1500 models, and it works on NOx and soot sensors with 24mm or 30mm hex sizes. It also serves well on similar diesel engines with limited access sensors.

• Designed specifically for 2014–current Ram 3.0L EcoDiesel V6 engines
• Fits NOx and soot sensors with 24mm and 30mm hexes
• Useful on other diesel applications with comparable clearances

Who is this for? Professional technicians, fleet mechanics, and knowledgeable DIYers who work on 3.0L EcoDiesel vehicles and need a purpose-built solution for sensors located behind wiring, brackets, or heat shields. If you frequently service NOx or soot sensors and require stronger drive tools plus better engagement to avoid damaging sensor hexes, the Lisle 12290 set offers targeted clearance, durable construction, and the socket options commonly required for these applications.
