$700 Core Charge Applies.
A $700 refundable core charge is added to this order. You must return your old turbo core to receive the refund. Customer is responsible for core return shipping costs. Do not order without a rebuildable core ready to return.

Cab Chassis Application Only.
This turbo is specifically for 2013-2018 Ram Cummins Cab Chassis trucks. Verify your exact application before ordering - this is not a universal Ram Cummins fitment.

The R8321377AA is a Genuine OE Mopar Cummins Holset turbocharger for 2013-2018 Ram Cummins Cab Chassis applications. This is a factory-original replacement - not an aftermarket equivalent or remanufactured unit - built to the same specification as the turbo that came on the truck. If OE fitment and factory-spec performance are the goal, this is the correct part.

Is This the Right Turbo for Your Truck?

Buy this if...

Your truck is a 2013-2018 Ram Cummins Cab Chassis and you want a genuine OE Mopar replacement turbo
You need factory-spec fitment and performance - this is a Genuine OE Mopar Cummins Holset unit, not aftermarket
You have a rebuildable core ready to return and can cover return shipping costs

Do not choose this if...

Your truck is a standard Ram pickup - this fitment is specific to the Cab Chassis application and is not interchangeable with the standard pickup platform
You are looking for an aftermarket upgrade or performance turbo - this is a genuine OE replacement built to factory specification
You do not have a rebuildable core to return or cannot cover core return shipping - the $700 core charge will not be refunded without a qualifying core return

Verify before ordering...

Truck is a 2013-2018 Ram Cummins Cab Chassis - not a standard Ram pickup
You have a rebuildable core ready to return
You are prepared to cover core return shipping costs

The $700 Core Charge - What You Need to Know Before Ordering

How the core charge works on this turbo:
A $700 core charge is added to your order at checkout. When your new turbo arrives, you return your old failed turbo (the core) using your own shipping account - return shipping is at your expense. Once the core is received and verified as rebuildable, the $700 is refunded. If you do not have a core to return or the core is not rebuildable, the charge is not refunded. Do not order this turbo without a core ready to go back.

This is a genuine OE replacement - the right choice for factory-spec restoration. If you need a performance upgrade or do not have a core to return, this is not the correct path.

Genuine OE Mopar vs Aftermarket - Why It Matters Here

This turbo carries the Genuine OE Mopar designation, meaning it is manufactured to the same specification as the original factory turbo. For buyers whose goal is a factory-spec restoration - not a performance upgrade - genuine OE is the correct choice. An OE replacement matches the original calibration, interfaces correctly with the truck's ECM and emissions systems, and carries the manufacturer's quality standards for that application.

If your goal is added performance ceiling or an upgraded turbo configuration, a genuine OE replacement is not what you are looking for. This is a like-for-like factory replacement.

Fitment Coverage

This turbo fits 2013-2018 Ram Cummins Cab Chassis applications. This is not a standard Ram pickup fitment. Cab Chassis trucks use a different configuration than the standard short bed and long bed Ram pickup platforms. Verify your exact application before ordering.

Avoid These Common Mistakes

Ordering without confirming the Cab Chassis application. This turbo is specifically for the Ram Cummins Cab Chassis, not the standard pickup. Ordering by year and engine alone without confirming the Cab Chassis application is the most common wrong-order on this part.
Ordering without a rebuildable core ready to return. The $700 core charge is not refunded without a qualifying core return. Do not order this turbo if you do not have a core available to send back.
Underestimating core return shipping costs. Core return shipping is the customer's responsibility. A turbo core is heavy freight - factor shipping costs into your total cost before ordering.
Expecting a performance upgrade. This is a genuine OE factory replacement. It restores the truck to stock specification. If you need an upgraded turbo, this is not the correct part.

Before You Place the Order

Truck is a 2013-2018 Ram Cummins Cab Chassis - confirmed, not a standard pickup
Rebuildable core is available to return
Core return shipping cost (at your expense) is accounted for
Goal is OE factory-spec restoration, not a performance upgrade

Checklist confirmed? The R8321377AA is the correct Genuine OE Mopar Cummins Holset turbo for your 2013-2018 Ram Cummins Cab Chassis.
