More about the prize:

ProMaxx DX  is taking the diesel market to places it has never been before! The DX Series cylinder head is a lighter and stronger 356-T6 aluminum version of what has always been a cast iron cylinder head. ProMaxx DX Series being strengthened in many areas and provides power gains and flow improvements, right out of the box. Machined and assembled in the USA.

Cylinder Heads Feature:

  • 18mm
  • Iron matrix valve guides honed to size for excellent lubrication and oil retention as well as maximum consistency in guide diameter for longevity. Our Guides are made with higher graphite content which is a lubricating component. This insures that the life of both valve stem and guide is solid for 100’s of thousands of miles, with worry-free service.
  • Upgraded heavy duty casting, thicker than OE Our Castings are made thicker in problematic areas that have known to fail to cause not only cracks but also leading to fuel contamination in the cooling system.
  • Pressure tested at 50 PSI and 210F and vacuum checked.
  • Blueprinted to proprietary valve train geometry, to alter valve height and valve recession for maximum reliability and longevity. Our Valve stem heights are altered to remove preload on the lifter and decrease the wear as well as help the lifters live a long life.
  • Resurface: We incorporate the use of profilometers to make sure that the smoothness and surface finish of the static area meets the Ra of the gasket manufacturer. This is mandatory for proper gasket sealing and keeps the head gasket from failing. Ra is an arithmetic average of the surface finish.
  • Pressure test: We already test our heads with this process so you can rest assured there is no chance of porosity failures that can be associated with casted parts. Do the job one time the right way!
  • Hardened seats:  75% of heat dissipation occurs through the seating area of the head. This is so important that the valve seat is made of proper metallurgy because it is the conduit to transfer heat from the valve into the cooling system. We only use the highest quality seats to maintain our quality. These hardened seats also fix the problem of cylinder head cracking that is so infamous with the factory integrated seat.


A receiver groove is machined into the deck surface of the heads and our USA made stainless wire is pressed into the groove- the wire protrudes from the groove applying extra pressure to all layers of the gaskets- sealing combustion pressure in the cylinder. It is reusable should you have the heads off of the engine for any reason in the future. Our oringed heads work with any standard off the shelf head gasket. WE do not require any special machining of the block just prep the deck surface ensuring the block is clean dry and flat. We do as manufacture however prefer the Felpro Head gasket. The oring provides a heat sink from the fire ring and conveys that heat obtained into the cooling system.


NEW USA made high-quality valves, springs, retainers, locks, valve stem seals, freeze plugs, glow plug sleeves and injector sleeves.

Valve spring pressure is tested and balanced to ensure consistent spring pressure across all valves

1 year warranty on heads
