Cannot Ship to California:
This camshaft cannot be shipped to California addresses. If you are in California, do not place this order.

The Hamilton 07-C-OEM-CR is a factory-equivalent replacement camshaft for 2003-2018 Dodge Ram 5.9L and 6.7L Cummins Common Rail engines. It holds the same lift and duration at .050 inch as the original equipment profile - restoring proper valve events, smooth idle quality, and predictable power delivery without altering drivability or adding valvetrain stress. Built for engine rebuilds, fleet maintenance, and daily drivers where stock-style cam behavior is the goal.

Is This The Right Camshaft For You?

Buy this if... you are rebuilding a 2003-2007 5.9L Common Rail or a 2007.5-2018 6.7L Cummins and need a direct OEM-equivalent cam that restores factory valve timing, idle quality, and drivability.
Do not choose this if... you want more lift, more duration, or a performance profile. This cam makes no power additions - it is a stock replacement only. If you want increased output, browse the Hamilton cam lineup for performance options.
Verify before ordering: confirm your engine is a Common Rail application (2003 or newer), confirm you are not in California, and confirm you are pairing this cam with Hamilton 1.45 inch lifters.

Decision Confidence Check
Best match if: rebuilding a Common Rail 5.9L or 6.7L Cummins and restoring OEM cam behavior is the only goal
Stop and verify if: you are unsure whether your engine is Common Rail, your address is in California, or you want more than stock power
Most important check before ordering: confirm Hamilton 1.45 inch lifters are included in your order - this cam requires them
Next step: if fitment and lifters are confirmed and you are outside California, this is the correct cam for your rebuild

Fitment Coverage

This camshaft covers two generations of Common Rail Cummins:

2003-2007 5.9L Common Rail Cummins
2007.5-2018 6.7L Cummins

This is a Common Rail application only. It does not apply to 12-valve or 24-valve VP44 engines built before 2003. If your truck predates the Common Rail platform, this is not the correct cam.

Required: Pair With Hamilton 1.45 Inch Lifters

Do Not Install This Cam Without the Correct Lifters:
Hamilton specifies this camshaft must be paired with Hamilton 1.45 inch lifters. Using incorrect or worn lifters with a new camshaft is one of the most common causes of premature cam lobe failure on Cummins rebuilds. Do not reuse old lifters. Order the Hamilton 1.45 inch lifters alongside this cam.

Pairing a new camshaft with old or mismatched lifters creates uneven contact patterns during break-in that can damage both the cam and the lifters. This is not a shortcut worth taking on a rebuilt engine.

What This Camshaft Restores

The 07-C-OEM-CR replicates the factory cam profile exactly - same lift, same duration at .050 inch, same timing relationship between intake and exhaust events. When a Cummins cam wears or fails, symptoms include rough idle, misfires, loss of compression-style feel, or valvetrain noise. Replacing with an OEM-equivalent profile restores the engine to the state it left the factory.

No modifications to drivability, no changes to valvetrain load, and no tuning adjustments required. This is a like-for-like replacement designed for long-term reliability on daily-driven, fleet, and high-mileage rebuilt engines.

OEM Replacement or Performance Upgrade - Know Which Path You Need

The 07-C-OEM-CR is the right call if your only goal is restoring factory cam behavior. It will not add power, change the powerband, or require any supporting modifications.

If you want more aggressive valve events, increased lift or duration, or a cam built for a performance or towing application, this is not the right part. See the Hamilton 188/220 Aggressive Street cam if you want more than stock. Choose the 07-C-OEM-CR if stock reliability and factory drivability are the goal.

Avoid These Common Mistakes

Reusing old lifters: Always install new Hamilton 1.45 inch lifters with this cam. Worn lifters on a new cam lobe will cause early failure.
Ordering by truck year alone: Confirm this is a Common Rail application. The 5.9L went Common Rail in 2003. Trucks before 2003 use a different cam entirely.
Ordering if you are in California: This part cannot ship to California. Verify your shipping address before placing the order.
Choosing OEM-profile when you want performance: This cam will not add power. Review the Hamilton performance cam lineup if power gains are the goal.

Before You Order - Confirm These

Engine is a 2003-2007 5.9L Common Rail or 2007.5-2018 6.7L Cummins
Shipping address is not in California
Hamilton 1.45 inch lifters are included in your order
Goal is OEM-equivalent cam replacement, not a performance upgrade

All four confirmed? The 07-C-OEM-CR is the correct cam - engineered to factory spec and built for long service life on any Common Rail Cummins rebuild.

Frequently Asked Questions

Click or tap a question below to expand the answer.

Does this camshaft fit both the 5.9L and 6.7L Cummins?

Yes. The Hamilton 07-C-OEM-CR covers 2003-2007 5.9L Common Rail Cummins and 2007.5-2018 6.7L Cummins engines. It does not fit pre-2003 12-valve or VP44 24-valve Cummins applications.

Do I need new lifters when installing this camshaft?

Yes. Hamilton specifies this cam must be paired with Hamilton 1.45 inch lifters. Reusing old or worn lifters with a new camshaft is a primary cause of premature cam failure on Cummins rebuilds. Always replace the lifters at the same time.

Will this camshaft add power or change the power delivery?

No. The 07-C-OEM-CR is a factory-equivalent profile with the same lift and duration at .050 inch as the original equipment cam. It restores stock valve events and drivability. It is not a performance camshaft and will not increase power output.

Does this cam require any tuning changes after installation?

No. Because this is an OEM-equivalent profile, it does not change valve timing, lift, or duration relative to the factory cam. No tuning adjustments are required.

Can this camshaft ship to California?

No. This item cannot be shipped to California. If your shipping address is in California, do not place this order.

What if I want a performance cam instead of a stock replacement?

If you want increased lift, duration, or a more aggressive valve event for a performance or towing build, the Hamilton 188/220 Aggressive Street Camshaft is a commonly chosen upgrade. Visit the Hamilton Cams Authority Hub at puredieselpower.com for the full lineup and selection help.

Is this camshaft suitable for a high-mileage engine rebuild?

Yes. This cam is engineered for long service life and is well suited for engine rebuilds, high-mileage restorations, and fleet applications where factory-equivalent behavior and durability are the priority. Pair it with new Hamilton 1.45 inch lifters for a correct installation.
