Heavy Duty Engine Parts

Heavy Duty Diesel and Natural Gas Parts – Starting as an OEM supplier of cast aluminum valve covers for large diesel engines in 1998, Airflow Systems has since expanded their product line to include multiple cast iron, cast aluminum and machined billet parts for diesel engine OEMs and diesel/natural gas engine rebuilders. Parts range from intake manifolds to turbocharger housings and are available as raw castings or fully machined parts.

Specializing in parts with an annual volume of up to 3000 units, we can develop tooling for parts where drawings or original tooling is not available. We utilize rapid tooling and conventional pattern making to match cost and delivery times to customer requirements.

In special circumstances we may share tooling costs with our customers in return for shared marketing rights. Contact us with your proposal.

Heavy duty engines were often shipped with pulleys made of cast iron which are prone to corrosion. On older engines the casting patterns for the pulleys specific to those engines have often been lost to wear and tear, damage or company ownership changes. Airflow Systems offers pulleys machined from appropriate alloy billets. They are inherently […]
