PDD Stage 1 Street Series 5.9L/6.7L Cummins Cylinder Head (24 Valve Common Rail) Bundle

This Power Driven Diesel Street Series Cylinder Head is an upgraded alternative to a stock remanufactured cylinder head for your 2003-2007 Dodge Ram 5.9L Cummins and 2007.5-2018 Dodge Ram 6.7L Cummins. The 6.7L Cummins Cylinder Head was designed to supersede the 5.9L Cylinder Head. For your ease and ours, PDD only offers the 6.7L Cummins Cylinder Heads due to its ability to work on both, just be sure to use the correct model year of head gasket that matches the cylinder block of your application.

Stock Cummins heads are notorious for dropping valve seats as they accumulate hard miles from heavy towing or street hot rodding.  The solution is hardened and oversized valve seats that won’t drop when you’re hauling or hot rodding!  Each PDD cylinder head is upgraded with hardened and oversized press-in valve seats, CNC valve job, new valve springs, and fully assembled with locks, retainers, and new valve seals.

Many hard-working tow rigs/haulers and hot-rodded street trucks have been sidelined by a blown or popped freeze plug under the valve cover which immediately mixes coolant and engine oil.  Power Driven Diesel uses threaded plugs in-lieu of soft/freeze plugs so you never have to worry about coolant leaks under the valve cover.  The PDD Street Series Cylinder Head is rated for up to 800 HP and guaranteed to meet or exceed factory specifications, giving you reliable performance.

Features:

• 11 threaded-in Freeze Plugs
• New Valve Springs
• New Cylinder Head
• New Heavy-Duty Valves
• Hardened Oversized Press-In Valve Seats
• CNC Valve Job
• 1 Year Limited Warranty

Note: If your engine or intended application exceeds the factory RPM limits, upgraded valve springs are recommended.
