Power Driven Diesel Street Series 5.9L-6.7l Cylinder Head – Bundle

This Power Driven Diesel Street Series 5.9L Cylinder Head is an upgraded alternative to a stock remanufactured cylinder head for your 2003-2007 Dodge Ram 5.9L Cummins.  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, new Cummins valve springs, new valve guide liners, and fully assembled with locks, retainers, and new valve seals. We also thoroughly inspect, pressure test, resurface and paint these Street Series Cylinder Heads so they arrive ready for installation.

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 the performance you can count on.
