The Alliant Power AP0162 is a turbocharger installation kit for 2001-2010 GM 6.6L Duramax - covering LB7, LLY, LBZ, and LMM engine codes across Silverado 2500HD, Silverado 3500HD, Silverado 3500, Sierra 2500HD, Sierra 2500HD Classic, and Express 2500 applications. This kit includes all the necessary gaskets and sealing components to complete a turbocharger removal and reinstall on the listed 6.6L Duramax platforms. No separate gasket sourcing is required for the core turbo R&R on these engine codes.

The Alliant Power AP0162 turbocharger installation kit fits 2001-2010 GM 6.6L Duramax LB7, LLY, LBZ, and LMM applications, providing all required gaskets and sealing components for a complete turbocharger removal and installation in one order.

Buy this if...

You are removing or replacing a turbocharger on a 2001-2010 6.6L Duramax LB7, LLY, LBZ, or LMM and want all required gaskets in one order.
You want a direct-fit kit that meets or exceeds OE specifications for the listed Duramax applications.

Do not choose this if...

Your Duramax is a 2011 or newer LML or LGH - those use the AP0165 instead.
You need the turbocharger itself - this is a gasket and sealing kit only.

Verify before ordering...

Engine code is LB7, LLY, LBZ, or LMM - not LML or LGH.
Model year falls within 2001-2010 and matches the application list below.

One Kit for All Four Gen 3 Duramax Engine Codes

Sourcing individual turbo gaskets across an LB7, LLY, LBZ, or LMM Duramax means tracking down multiple sealing components across different OE numbers. The AP0162 consolidates them into a single order for the 2001-2010 6.6L Duramax platform. All components meet or exceed OE specifications. If your truck falls in the 2001-2010 model year range and carries one of the four confirmed engine codes, this is the correct install kit to order.

The AP0162 covers 2001-2010 only. For 2011-2016 LML and LGH Duramax applications, the correct kit is the AP0165, which is a separate product. Confirm your model year and engine code before ordering - both must match.

All Required Gaskets Included: Complete sealing kit for turbo removal and reinstall on LB7, LLY, LBZ, and LMM

Meets or Exceeds OE Specs: Engineered to OE fit, form, and function standards

Made in USA: Domestic assembly

Gasket Kit Only: Turbocharger unit is a separate purchase

Avoid These Common Ordering Mistakes

Most Common Mistake: Ordering AP0162 for a 2011 or newer Duramax
The AP0162 covers 2001-2010 LB7, LLY, LBZ, and LMM engines only. The 2011-2016 LML and LGH engines require the AP0165, which is a different kit. Confirm your model year and engine code before ordering.

Assuming this kit includes the turbocharger - the AP0162 is a gasket and sealing kit only. The turbo unit is a separate purchase.
Confusing the AP0162 with the AP0165 - the AP0165 is the correct kit for 2011-2016 LML and LGH applications. They are not interchangeable.
Not confirming which engine code your truck has - LB7, LLY, LBZ, and LMM are all covered, but 2011+ LML and LGH are not. Check the 8th digit of your VIN to confirm engine code before ordering.

Before You Order - Final Confirmation

Engine code confirmed: LB7, LLY, LBZ, or LMM - not LML or LGH
Model year confirmed: 2001-2010 and within the listed application range
Turbocharger gaskets confirmed included - no separate turbo sealing kit purchase required for this engine

For a 2001-2010 GM 6.6L Duramax LB7, LLY, LBZ, or LMM turbocharger removal and reinstall, the AP0162 is the correct one-kit solution to order.

Frequently Asked Questions

Click or tap a question below to expand the answer.

What Duramax engine codes does the AP0162 fit?

The AP0162 fits LB7 (2001-2004), LLY (2004.5-2005), LBZ (2006-2007), and LMM (2007.5-2010) engine codes on the 6.6L Duramax. It does not cover 2011 and newer LML or LGH engines - those use the AP0165.

Does the AP0162 include the turbocharger itself?

No. The AP0162 is a gasket and sealing kit only - it includes all required sealing components for a turbocharger removal and reinstall. The turbocharger unit is a separate purchase.

Will the AP0162 fit my 2007 Silverado 2500HD with the LMM?

Yes - provided your 2007 Silverado 2500HD carries the LMM engine code. The LMM began production in 2007.5 in the GMT 900 body style. If your truck is a 2007 early production with an LBZ, the AP0162 also covers the LBZ. Both engine codes are confirmed for this kit. Check the 8th digit of your VIN to confirm which engine code you have.

What is the difference between the AP0162 and the AP0165?

Year range and engine codes. The AP0162 covers 2001-2010 6.6L Duramax LB7, LLY, LBZ, and LMM. The AP0165 covers 2011-2016 6.6L Duramax LML and LGH. These are different engine generations with different turbo gasket requirements. Order the kit that matches your engine code - they are not interchangeable.

Is 172-784-0131 the same as the Alliant Power AP0162?

Yes. Part number 172-784-0131 and 1727840131 are on the confirmed cross-reference list for the Alliant Power AP0162 turbocharger installation kit. If your existing kit or invoice shows either of those numbers and your truck is a 2001-2010 6.6L Duramax LB7, LLY, LBZ, or LMM, the AP0162 is the correct replacement.

Does the AP0162 fit the GMC Sierra 2500HD Classic?

Yes. The 2007 GMC Sierra 2500HD Classic is on the confirmed fitment list for the AP0162. This refers to the carry-over GMT 800 platform sold alongside the new GMT 900 body style in the 2007 model year. Confirm your engine code is LBZ or LMM before ordering.
