Moker Duramax Turbo Vane Position Sensor Socket for 6.6L Duramax (2004+) — 1" 6-Point Split Design, 66mm Reach

The Moker Duramax Turbo Vane Position Sensor Socket is a purpose-built split socket tool for removing and installing the turbo vane position sensor on 2004 and newer Duramax and Isuzu F-Series 6.6L diesel engines.

When working around the turbocharger on Chevrolet, GMC, or Isuzu diesel trucks, access is often the biggest obstacle. This socket was engineered to reach the sensor hex located between the turbo’s cold and hot housings without cutting wires or fighting clearance. It combines a deep, slim profile with a split design so technicians and DIYers can service the Part# 12643471 vane position sensor cleanly and quickly.

How does this tool get into cramped turbo locations?

The socket’s narrow 66mm length and 1" (25.4mm) 6-point opening are sized to slip into the narrow gap between the turbo’s housings. The split-body shape allows the socket to be moved around the sensor wire and connector, so you won’t have to disconnect or risk damaging the harness while removing the sensor.

• 66mm overall length for deep reach into tight turbo cavities
• 1" (25.4mm) 6-point hex to match the sensor head precisely
• Split socket design for working around wires and connectors
• Designed specifically for Duramax/Isuzu vane position sensor (Part# 12643471)

Will it fit my truck model and drive tool?

This socket is made for 6.6L Duramax engines (LLY, LBZ, LMM, LML) and Isuzu F-Series diesel engines from 2004 onward. It accepts a common 3/8" square drive ratchet or extension, so it plugs directly into most professional and consumer toolsets without adapters.

• Compatible with Duramax LLY, LBZ, LMM, LML 6.6L engines
• Works on Isuzu F-Series diesel turbochargers 2004 and newer
• 3/8" square drive fits standard ratchets and extensions
• Intended for the turbo vane position sensor Part# 12643471

How does the construction affect durability and precision?

Manufactured from durable 42CrMo alloy steel, the socket resists wear, corrosion, and deformation under torque. Its 6-point internal geometry reduces rounding of the sensor hex, giving a secure fit that minimizes slippage during removal and installation.

• 42CrMo steel for high strength and corrosion resistance
• 6-point socket shape reduces rounding and improves grip
• Split-body engineering protects the sensor wire and connector
• Precision-machined for repeatable, accurate engagement

What practical benefits will I notice during service?

You’ll spend less time struggling for access and more time completing the job. The socket’s combination of depth, split access, and corrosion-resistant material means quicker sensor swaps with lower risk of damaging components around the turbo.

• Speeds up sensor removal and installation in confined areas
• Prevents damage to fragile sensor wiring and connectors
• Reduces the need for disassembly of surrounding components
• Long-lasting construction minimizes tool replacement frequency

Who is this for: The Moker Duramax Turbo Vane Position Sensor Socket is aimed at professional mechanics, fleet technicians, and hands-on truck owners who service Chevrolet, GMC, and Isuzu diesel trucks. If you frequently work on 6.6L Duramax or Isuzu F-Series turbos and need a reliable, purpose-made tool to access the vane position sensor without harming wiring or nearby parts, this socket is designed for you.
