New Castings Left Dodge Jeep Cherokee Ram 1500 Durango Dakota 4.7L V8 SOHC Cylinder Head (Valves and Springs Only)

New Castings Left Dodge Jeep Ram 1500 Durango Dakota 4.7L V8 SOHC Cylinder Head

High-Performance Replacement Head Assembled with Valves and Springs

Restore your engine’s peak compression and thermal efficiency with this brand-new aftermarket left-hand (LH) driver-side cylinder head, specifically engineered for the 1999–2007 Chrysler, Dodge, and Jeep 4.7L SOHC PowerTech V8 engine series. Unlike remanufactured units that may have already undergone multiple thermal cycles, this “zero-hour” casting provides a fresh structural foundation, eliminating the risks of previous fatigue, micro-cracking, or the “dropped valve seat” issues common in high-mileage factory iron or aluminum heads.

This cylinder head arrives pre-assembled with high-quality valves and calibrated springs to ensure a seamless “drop-in” experience. For maximum versatility, each unit includes a precision-fit EGR block-off plate, ensuring 100% compatibility across both EGR and non-EGR engine configurations. Utilizing a premium high-density aluminum alloy, the 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 and optimal volumetric efficiency for the LH cylinder bank.

🛠️ 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.
