New Castings Pair Dodge Jeep Cherokee Ram 1500 Durango Dakota 4.7L V8 SOHC Cylinder Heads (1999-2007)

New Pair Dodge Jeep Chrysler 4.7L V8 SOHC Cylinder Heads (1999–2007)

Premium New Casting Replacement for 4.7L PowerTech Engines

Restore your engine’s peak compression and thermal efficiency with this matched pair of brand-new aftermarket cylinder heads, specifically engineered for the Chrysler, Dodge, and Jeep 4.7L SOHC PowerTech V8 engine series. Unlike remanufactured units that may have already undergone multiple thermal cycles, these “zero-hour” castings provide a fresh structural foundation, eliminating the risks of previous fatigue, micro-cracking, or the catastrophic “dropped valve seat” issue prevalent in high-mileage factory castings. Each head features reinforced internal walls and upgraded, hardened valve seats to ensure long-term seat retention and peak combustion efficiency.

This cylinder head pair arrives “Fully Loaded” and ready for immediate installation, pre-assembled with high-quality valves and calibrated springs to ensure a seamless “drop-in” experience across both engine banks. Utilizing a premium high-density aluminum alloy, each head is precision-machined to meet or exceed original equipment (OE) dimensional tolerances, ensuring an absolute deck surface finish for a superior head gasket seal. Whether you are performing a comprehensive top-end overhaul on a Jeep Grand Cherokee, Dodge Ram 1500, or Durango, this brand-new PowerTech pair provides the structural integrity and cooling capacity required to regain your 4.7L V8’s original reliability.

🛠️ In-House Machining Process

• Debris-Free Preparation: Every new casting is chemically cleaned and blown out to remove all residual machining oils, metal shavings, and manufacturing debris. This ensures your oiling system remains uncontaminated from the first start-up.

• In-House Precision Machining: Unlike “shelf-stock” heads, we perform all final machine work in-house. This includes final guide sizing and precision valve seat cutting to ensure perfect geometry and clearances before the head reaches the assembly bench.

• Pressure & Integrity Testing: To go beyond the factory standard, we pressure-test every head to 60 PSI. This verifies that the casting is free of porosity leaks or internal defects that could compromise the cooling or oiling systems.

• Dimensional Inspection: Our technicians perform a multi-point inspection of the gasket-sealing surface and bore alignment. This ensures the head is perfectly flat and meets tight OEM tolerances for a flawless fit.

• Professional Assembly & Setup: Valvetrain components are installed and verified in a clean-room environment. We check spring heights and seal seating to ensure the assembly is balanced and ready for high-performance use.

• Vacuum-Seal Verification: Every intake and exhaust port is Vacuum Tested. This guarantees a 100% airtight seal between the valves and seats, ensuring maximum compression and peak performance right out of the box.
