All our cores are hand-built in our own factory, designed and developed to perfectly suit the vehicle they are fitted to. Our radiator tubes are internally clad with 7072 corrosion resistant material to radically improve life in-service and our oil coolers all have internal turbulators to ensure maximum strength and heat rejection.
We are one of the only suppliers in the UK to manufacture the original radiator pressings for our products, by using tooling that originated from the 1960s, this allows us to give the customer accurate specifications to the original designs that went into their classic cars.
The whole creative process from design, manufacture and dispatch is handled in house with a diverse team of knowledgeable professionals. For more details please visit our specific pages.
