Moker Duramax Turbo Vane Position Sensor Socket 1in 6-Point 66mm Split Design for 6.6L Duramax & Isuzu

The Moker Duramax Turbo Vane Position Sensor Socket is a purpose-built, split-design 1" 6-point deep socket that removes and installs the turbo vane position sensor on 2004‑up Duramax and Isuzu F‑Series diesel turbos without damaging the sensor wire.

If you work on 6.6L Duramax engines (LLY, LBZ, LMM, LML) or Isuzu F‑Series diesels from 2004 onward, gaining access to the turbo vane position sensor is often the hardest part. This tool was engineered to fit the narrow gap between the cold and hot sides of the turbocharger and engage the OEM sensor hex (Part# 12643471) without requiring disassembly of surrounding components.

How does this socket make sensor removal easier?

The split socket profile slips around the sensor body and wire, allowing you to turn the sensor hex while protecting the wiring harness. Its deep, 6‑point design holds the sensor securely so you can apply torque without rounding corners.

• Split socket lets the harness stay in place during removal
• 1" (25.4mm) 6‑point size matches the OEM sensor head
• 66mm length reaches recessed sensor locations
• 3/8" square drive fits common ratchets and extensions

Will this tool fit my Duramax or Isuzu turbocharger?

Yes — the socket is tailored for 6.6L Duramax engines (LLY, LBZ, LMM, LML) and Isuzu F‑Series diesel turbos from 2004 and later that use the factory vane position sensor (Part# 12643471). Measure your sensor hex to confirm a 1" fit if unsure.

• Compatible with Chevrolet/GMC Silverado and Sierra 6.6L Duramax
• Fits Isuzu F‑Series turbos using the same sensor design
• Designed for sensors recessed between turbo cold and hot housings

What are the build and drive specifications?

The socket is constructed from heat‑treated 42CrMo alloy steel for strength and corrosion resistance under workshop conditions. It uses a 3/8" square drive and the 6‑point 1" hex geometry to reduce slippage on the sensor head.

• Material: high‑strength 42CrMo steel for durability
• Drive: 3/8" square drive — compatible with common ratchets
• Dimensions: 1" (25.4mm) 6‑point, 66mm overall length
• Split design protects sensor wiring during use

How does this compare to generic sockets?

Generic sockets often lack the split opening or correct depth, forcing technicians to remove turbo components or risk cutting wires. The Moker tool eliminates those extra steps by matching the OEM sensor geometry and providing adequate clearance for tight turbo housings.

• Engineered specifically for turbo vane position sensors — not a one‑size‑fits‑all socket
• Deep reach and accurate hex profile prevent slipping and rounding
• Split body avoids bending or chafing sensor wiring

Who is this for? This socket is built for diesel truck owners, fleet technicians, and independent mechanics who service 6.6L Duramax and compatible Isuzu turbos. If you routinely diagnose or replace turbo vane position sensors on 2004‑up Duramax or Isuzu F‑Series engines, this tool reduces removal time, protects delicate wiring, and prevents unnecessary turbo disassembly.
