Fleece 6.7 L Freedom‑Series Cummins Cylinder Head (STREET) | 2007.5-2018 Ram 2500/3500

Refresh your 6.7 L Cummins with a fully remanufactured Freedom‑Series STREET cylinder head. Machined and assembled in Fleece’s state‑of‑the‑art facility, each head is pressure‑checked, decked, painted, and fitted with hardened oversize valve seats, new guide liners, and genuine Cummins springs. Eleven screw‑in freeze plugs eliminate the under‑valve‑cover coolant leaks that plague factory castings, while the 700 hp rating makes this head ideal for daily‑driven and heavy‑tow builds.

Key Features

• Hardened, oversize press‑in valve seats – resist seat recession in high‑EGT use.
• New Cummins valve springs & guide liners – OE durability right out of the box.
• Decked & multi‑angle valve job – ready to seal MLS gaskets without additional machine work.
• Street‑rated to ≈ 700 hp; choose Performance Series for higher RPM or boost.
• 1‑year limited parts warranty.
