6.7L Freedom Series 07.5-18 Dodge RAM 2500/3500 Cummins Cylinder Head Street Fleece Performance
Freedom Series Cylinder Heads
Give new life to your engine with our fully re-manufactured Cummins Cylinder Heads. Each head is manufactured in our state-of-the-art cylinder head machine shop and guaranteed to meet or exceed factory specifications.
All heads are inspected, pressure checked, decked, painted, and ready for installation. Plus, the 11 screw-in freeze plugs ensure that you will never worry about a coolant leak under the valve cover again.
Perfect for a daily driver or heavy duty towing, our Street Heads are rated for use up to 700hp. If your engine configuration is exceeding factory RPM limits, a Performance Series head with higher valve spring rates is required.
Freedom Series Street Heads Include:
- 11 Screw-in freeze plugs (eliminates coolant leaks)
- Hardened, oversized press-in valve seats
- New Cummins valve springs
- New valve guide liners
Head gasket is not included; we recommend the use of Cummins 4932210.
Core and crate return required - all paperwork and instructions for return are included with the new cylinder heads. You are responsible for all return shipping costs of the core.
Please follow ALL installation instructions; Valve lash is required. Be sure to back off adjusters on rocker arms, or damage will occur to the cylinder heads. For all applications over stock horsepower, we recommend the use of ARP625 or ARP L19 12mm head studs.
