California / Colorado Shipping Restriction - Lead Time Notice
This turbo cannot be shipped to a California or Colorado delivery address; an eligible out-of-state address is required. If a powder coated cover option is selected, lead time may be extended - plan accordingly before ordering.

The DDP D06-T642-001 is a 100% drop-in Stage 2 64mm turbocharger for the 2017-2023 L5P Duramax - engineered to push your build toward the 700-750 HP range without any housing modifications or custom piping. Featuring a DDP-exclusive 63.5mm billet compressor wheel, a 9 or 10 blade 76x68mm turbine wheel, and a DDP-exclusive vane assembly, this is the correct upgrade path for L5P owners whose builds have outgrown the factory turbo's ceiling. No core charge applies.

The DDP D06-T642-001 is a bolt-on L5P turbo upgrade for 2017-2023 Chevy and GMC 6.6L Duramax trucks; it is rated 700-750 HP, ships brand new with no core return required, and includes the option to install a new vane actuator or reuse your existing known-good unit.

Buy this if...

Your 2017-2023 L5P build is targeting 700-750 HP and you need a drop-in turbo upgrade.
You're running or planning 50% over injectors and want a turbo that can match that fueling.
You want a new turbo with no core return hassle and a limited lifetime warranty.

Do not choose this if...

Your L5P is stock or lightly modified and you only need a stock-spec replacement - a stock-style unit is the correct path.
Your build goal is under 600 HP; this turbo is built for the upper power tier and may not suit a milder tune.
Your shipping address is in California or Colorado - an eligible out-of-state delivery address is required.

Verify before ordering...

Your truck is a 2017-2023 L5P Duramax - this fitment does not cover prior Duramax generations.
Your injector size and tune support the 700-750 HP range; 50% over injectors are recommended to reach max potential.
Whether you'll reuse your existing actuator or want the new actuator included - choose accordingly at purchase.

Is This the Right Stage for Your L5P Build?

The DDP Stage 2 64mm is the correct turbo when your L5P build is built around real power - not a stock-style restore. This is a purpose-built upgrade for trucks targeting 700-750 HP, where the factory turbo has become the limiting factor. DDP rates this turbo at 700-750 HP and recommends pairing it with 50% over injectors to reach that ceiling. If your fueling is not there yet, the turbo will still drop in - but you won't be unlocking its full range until the rest of the fuel system keeps up.

Stay with a stock-spec L5P turbo replacement if your goal is factory reliability, a bone-stock power level, or a straightforward like-for-like swap. This Stage 2 unit is built for the modified build, not the stock restore path. If your build is growing and the factory turbo is now the weak link, confirm your injector sizing matches, then this is the right turbo to order.

No Core Charge: Brand new unit - keep or recycle your old turbo locally

Limited Lifetime Warranty: Manufacturer-backed coverage on this turbo

Drop-In Fit: 2.5" stock-appearing, 100% bolt-on for 2017-2023 L5P

ISO Balanced: Balanced to ISO specification before shipment

What Makes the DDP Stage 2 64mm Stand Out

The D06-T642-001 is built around hardware DDP developed specifically for the L5P platform, not a generic core dressed up with a sticker. The 63.5mm billet compressor wheel is a DDP-exclusive design, and the vane assembly is also DDP-exclusive - both engineered to move more air through a stock-appearing 2.5" housing that bolts directly to the factory location. The liquid-cooled center section and heavy-duty bearings with 360-degree thrust bearing are there to handle the thermal and mechanical load that comes with running at this power level.

The turbine side runs a 9 or 10 blade 76x68mm wheel. The entire assembly is balanced to ISO specification. For builds in the 700-750 HP range on the 2017-2023 L5P Duramax, this is the correct drop-in upgrade to order.

2017-2023 L5P Duramax Fitment

The DDP D06-T642-001 fits the 2017-2023 6.6L L5P Duramax - the current-generation variable geometry turbo platform found in Chevy Silverado 2500HD, Silverado 3500HD, GMC Sierra 2500HD, and Sierra 3500HD applications.

2017-2023 Chevrolet Silverado 2500HD / 3500HD - 6.6L L5P Duramax
2017-2023 GMC Sierra 2500HD / 3500HD - 6.6L L5P Duramax

This fitment covers the L5P generation only. Prior Duramax generations (LB7, LLY, LBZ, LMM, LML) use different turbo platforms and are not covered by this part number.

Avoid These Common Mistakes

Ordering without verifying injector size - DDP recommends 50% over injectors to reach the 700-750 HP ceiling. Ordering this turbo into a stock-fueled truck leaves significant potential on the table.
Assuming this covers pre-L5P Duramax trucks - the LML, LMM, LBZ, and earlier generations use a different turbo design and are not compatible with D06-T642-001.
Forgetting the actuator choice - decide at purchase whether to include the new vane actuator or reuse your known-good OEM unit. This affects what ships in the box.
Ordering with a California or Colorado delivery address - this turbo cannot ship to CA or CO addresses. Have an eligible out-of-state address ready before ordering.

Injector Size Check:
This turbo is designed for the 2017-2023 L5P with a recommended injector size of 50% overs to reach max potential. Running this turbo on a stock-fueled truck will not unlock its 700-750 HP rating - confirm your fuel system is matched before ordering.

Final Order Checklist

Truck confirmed: 2017-2023 6.6L L5P Duramax
Build target confirmed: 700-750 HP range
Injector sizing reviewed: 50% overs recommended for max potential

Shipping address confirmed: not a California or Colorado delivery address

For a 2017-2023 L5P Duramax build targeting 700-750 HP with matched fueling, the DDP D06-T642-001 Stage 2 64mm is the correct drop-in turbo to order.

Frequently Asked Questions

Click or tap a question below to expand the answer.

Will the DDP D06-T642-001 fit my 2017-2023 L5P Duramax without any modifications?

Yes - the D06-T642-001 is a 100% drop-in turbo for the 2017-2023 6.6L L5P Duramax. It uses a 2.5" stock-appearing housing and bolts directly to the factory location with no custom piping or housing modifications required. This fitment covers Chevy Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD with the L5P engine only - prior Duramax generations are not covered.

Does the DDP Stage 2 L5P turbo come with the actuator?

The new vane actuator is available with this turbo - you choose at purchase whether to include it or reuse your existing known-good actuator. If your current actuator is in good working condition, you can save cost by reusing it. If you want a fresh unit installed from the start, select the new actuator option when ordering.

What injector size do I need to hit 700-750 HP with this turbo?

DDP recommends 50% over injectors to reach the full 700-750 HP potential of the D06-T642-001. The turbo will drop in and function on a truck not yet at that injector size, but max power potential is only unlocked when the fueling matches. If your build is not yet at the 50% over mark, confirm your full build plan before ordering this stage.

Is there a core charge on this turbo?

No - the D06-T642-001 ships brand new with no core charge and no core return required. Keep your old turbo, recycle it locally, or do whatever you want with it. No deposit, no return paperwork.

My L5P is losing power and boost - is this the right part to fix it?

If your L5P is showing low boost, power loss, or surging boost pressure, a worn or failing VGT turbo is a common cause on this platform - and the D06-T642-001 is the correct drop-in replacement and upgrade path for 2017-2023 L5P trucks. However, this Stage 2 unit is built for the 700-750 HP range and is best matched to a modified build with 50% over injectors. If your truck is otherwise stock and you only need a stock-spec restore, a stock-replacement L5P turbo may be the better fit. Verify the cause of the power loss before selecting a stage.

Can I order the DDP D06-T642-001 if I live in California or Colorado?

This turbo cannot be shipped to a California or Colorado delivery address. Buyers in CA or CO must provide an eligible out-of-state shipping address for the order to be fulfilled. If you cannot provide an eligible delivery address, this order cannot be processed.

What warranty does the DDP D06-T642-001 come with?

The DDP D06-T642-001 comes with a Limited Lifetime Warranty. For full terms and conditions, contact Dan's Diesel Performance directly - warranty specifics beyond the stated Limited Lifetime coverage are not detailed in the product listing.
