Product Description
Serious top-end Cummins cam. The Hamilton Cams 07-C-220/240 steel core is built for high-RPM 5.9L/6.7L builds where you want big airflow up top. Typical operating range is ~3,500–5,200 RPM and it shines in drag and 3.0-class sled-pull applications when paired with the right head, turbo, and fuel.
Fitment
- 1989–2018 Ram 2500/3500/4500/5500 with 5.9L or 6.7L Cummins (12V & 24V), all drivetrain configurations.
- Steel core camshaft. Check cam tunnel bushings/clearance and verify piston-to-valve before final assembly.
What’s Included
- Hamilton Cams 07-C-220/240 steel camshaft (cam only).
Required / Recommended Supporting Parts
- Billet DLC-coated tappets (required): Hamilton 07-T-002
- Valve springs (choose per RPM):
- Hamilton 07-S-110 110# springs for >4,500 RPM/high-RPM use.
- Hamilton 07-S-003 103# springs for moderate RPM builds.
- Pushrods: Hamilton 07-P-004 Extreme Duty
- Cam retention: Hamilton 07-C-002 bolt-on retainer
Installation Notes
- Intended for high-RPM builds; fly-cut pistons (.200" valve relief) typically required. Always clay/measure clearance.
- Prime oil system, use proper assembly lube, verify oil pressure before first fire, then heat cycle and set lash.
Cross-Reference / Alternatives
- Street/Tow steel alternative (wider usable band): Hamilton 07-C-188/220S
- Budget cast version of the street/tow grind: Hamilton 07-C-188/220 (cast)
- 24V combo kit (cam + valvetrain): Hamilton 07-CC-24V188 Combo
FAQ
Who is this cam for?Builders targeting ~3,500–5,200 RPM with excellent flowing heads, strong turbo, fueling, and valvetrain control. It prioritizes top-end power for drag and sled-pull duty.
Do I need to fly-cut pistons?Yes—.200" valve reliefs and careful P-to-V checks are typically required for this profile. Always clay and measure your combo.
Are billet DLC tappets really required?Yes. This grind must be run with billet steel DLC-coated tappets. We pair it with Hamilton 07-T-002 for durability at high spring pressure.
Which springs should I use?For high-RPM use (>4,500), choose 110#. Moderate RPM builds may use 103#. Always verify coil bind and installed height.
What else should I replace while I’m in there?Strongly consider pushrods and a bolt-on retainer for stability at RPM.
