Additional Info

New Pair Jeep Dodge Chrysler 3.7L SOHC Cylinder Heads – Valves & Springs Only

Upgrade both sides of your 3.7L PowerTech engine with this premium pair of cylinder heads, featuring reinforced hardened valve seats to eliminate the primary cause of engine failure.

This matching pair of brand-new cylinder heads is the ultimate cost-effective solution for Jeep, Dodge, and Chrysler owners. Specifically engineered to fix the notorious factory flaw where OEM valve seats drop and destroy the engine, our heads are built with hardened valve seats for permanent reliability. These universal castings are a direct bolt-on for all 2002–2013 3.7L SOHC engines, compatible with both EGR and Non-EGR systems.

🛠️ 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: We perform all final machine work in-house, including precision valve seat cutting and guide sizing, to ensure perfect geometry and clearances.
  • Pressure & Integrity Testing: To go beyond the factory standard, we pressure-test every head to 60 PSI. This verifies 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 head is perfectly flat and meets tight OEM tolerances.
  • Professional Assembly: Valvetrain components are installed in a clean-room environment. We check spring heights and seal seating to ensure the assembly is balanced and ready for 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 performance.
