OEM Detroit Series 60 Marine Camshaft (825HP)

Re-Polished / Remanufactured – High Lift Performance Upgrade

Looking to wake up your 12.7L? This OEM re-polished/reman camshaft was factory-equipped in the legendary 825HP marine versions of the Detroit Diesel Series 60 — and it’s become a proven performance upgrade for on-road trucks running DDEC 2, 3, 4, and even DDEC 5 platforms.

This is not an aftermarket experiment. It’s a genuine OEM marine camshaft professionally reconditioned and polished, bringing factory durability with aggressive marine lift and timing characteristics - no core due!

Why Run the 825HP Marine Cam?

The 825HP marine engines were designed for sustained high-load operation. That means:

• Increased airflow potential
• Improved cylinder filling
• Stronger top-end power
• Proven OEM reliability

When paired with the right turbo and injector combination, this camshaft helps your Series 60 breathe like it should — especially in performance-oriented street or competition builds.

⚙️ Fitment & Compatibility

This camshaft will install in:

• DDEC II
• DDEC III
• DDEC IV
• DDEC V (with adapter)

Important Notes:

• Requires the larger cam bolt
• Must use the correct cam hub
• DDEC 5 applications require an adapter

If you're unsure about your hub or bolt size, reach out before ordering — we’ll make sure you get the correct setup.

Remanufactured to OEM Standards

Every camshaft is:

• Professionally inspected
• Precision re-polished
• Checked for proper journal condition
• Ready for installation

This is OEM Detroit hardware brought back to life — not offshore castings, not questionable regrinds.

Why It’s Popular for On-Road Trucks

Although originally marine-spec, this cam has become a sought-after upgrade for:

• 12.7L performance builds
• High horsepower street trucks
• Turbo upgrades (S400 frame or larger)
• Injector upgrades (7014's, 7315's or similar)

It’s a serious cam for serious builds.
