New Pair Jeep Dodge 3.7 SOHC Cylinder Heads with Head Gasket & Bolts (Valves and Springs Only)

New Pair Jeep Dodge Chrysler 3.7L SOHC Cylinder Heads – w/ Gaskets & Bolts (Valves/Springs Only)

Restore your engine’s integrity with this complete top-end gasket and head kit—featuring reinforced hardened valve seats to prevent the common 3.7L “dropped seat” engine failure.

The Chrysler 3.7L PowerTech V6 is a workhorse, but factory heads are notorious for dropping valve seats, which typically results in catastrophic engine damage. Our premium replacement heads are engineered with hardened valve seats to fix this flaw permanently. This specific package includes a high-quality head gasket set and head bolts, allowing you to perform a professional installation while reusing your existing cams and rockers. These universal castings fit all 2002–2013 3.7L SOHC engines, including both EGR and Non-EGR versions.

🛠️ In-House Machining Process

• Debris-Free Preparation: Every new casting is chemically cleaned and blown out to remove all residual machining oils and manufacturing debris, ensuring your oiling system remains uncontaminated.
• In-House Precision Machining: All final machine work is performed in-house, including precision valve seat cutting and guide sizing for perfect geometry and clearances.
• Pressure & Integrity Testing: We pressure-test every head to 60 PSI to verify that the casting is 100% free of porosity leaks or internal defects.
• Dimensional Inspection: Our technicians perform a multi-point inspection of the gasket-sealing surface to ensure the heads are perfectly flat and meet tight OEM tolerances.
• Professional Assembly: Valvetrain components are installed and verified in a clean-room environment. We check spring heights and seal seating to ensure the assembly is ready for immediate use.
• Vacuum-Seal Verification: Every intake and exhaust port is Vacuum Tested. This guarantees a 100% airtight seal between the valves and seats for maximum compression and fuel efficiency.
