New Heavy Duty Cylinder Heads - Alberta & BC

Behind The 8

We specialize in heavy duty cylinder heads for Cat, Cummins and Detroit applications.

 We’ve partnered with Jereh Power-Tech to provide heavy duty diesel engine cylinder heads throughout Alberta. Together we are setting a new standard for aftermarket cylinder heads

Many companies and customers have been enduring the challenge of finding new cylinder heads in Alberta that meet or exceed the current market standard. Look no further. Our manufacturer, Jereh Power-Tech, has optimized performance by improving the manufacturing process and quality control system to make our cylinder heads more reliable and durable.

Our heads have been designed for better cooling and liquid flow.

These are new castings… so no previous heat cycles. 

These heads are not remanufactured… so there are no core costs involved. 

The casting material we use is optimized to endure higher temperatures to insure lasting durability. This allows for a 30% coolant increase which provides cooler engine running temperature. The tensile strength of the updated valve material is two times the standard material. This enables the casting to work under higher temperatures of up to 850 degrees Celsius. 

We provide improved injector sleeve material and O rings to avoid leaks between the cylinder head cooling jacket and the injector bore. Also, a reliable valve guide seal to avoid leakage. The Inconel based valve material and improved seat material help us to achieve a 180% higher tensile strength as opposed to standard. We have reinforced the interior weak position of the casting, increasing strength. The smooth transitions effectively prevent the leakage caused by cracks on the joint surface under high pressure. The caps fit in tight specification without any interference with the cam shaft.

Frequently Asked Questions

Are these heads available in Alberta? 

YES, By maintaining a large inventory, we have the benefit of being able to serve our customers quickly and efficiently. No waiting months heads. No importation. No exchange rates or tariffs.

What kind of warranty do these heads have?

We stand behind our cylinder heads…  and our customers. All cylinder heads come with a 13-month warranty. If warranty is required, the process is as follows. We require a video of the serial number on the front of the damaged head as well as the damaged area. We require up to 48 hours for our engineering department to assess the damage. Once we have determined the defect has been caused by a fault on our end, we will ship a new head out to your head office or the initial location it was purchased from. 

What about prices?

We are extremely competitively priced compared to other vendors in our area and have a couple extra perks as well like free local, same day delivery.  Contact us today for individual item pricing.
