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

• Cleaning: Fully disassembled and thermally cleaned.
• Soda Blasted: Castings are blasted with Sodium Bicarbonate. Because baking soda is water-soluble, there is zero risk of abrasive media clogging oil passages.
• Pressure Testing: Tested to 60 PSI to ensure no cracks or porosity leaks.
• Surfacing: All heads are resurfaced on our Rottler S85A for a precision gasket-sealing surface.
• Valve Job: Multi-angle valve job performed; every port is Vacuum Tested to ensure valves are seated 100% airtight.
