A Reputation Built on Superb Craftsmanship

A Reputation Built on Superb Craftsmanship:

Since 1955, Hillcrest Camshaft Service has been supplying diesel engine rebuilders all over the world with precision remanufactured camshafts, fuel injection cams and lifters. Our products earn the Durabuilt name because the processes we use make them more durable and ensure a longer life.

The precision machinists at Hillcrest Camshaft Service bring a combined 125 years of hands-on, real-world experience to their craft. Pride in workmanship, dedication to quality and commitment to our longtime customers...that's the recipe for success that has turned this small family-owned business into a world leader in diesel camshaft...and now crankshaft remanufacturing.

Straightening Process :

Having the proper straightening and welding equipment is important, but having the proper training is just as important. Our technicians have been factory trained by Gleason Engineering staff.

Welding Process :

Not only do we have the ability to repair induction hardened steel diesel crankshafts, but we also repair outboard motor, compressor and cast iron crankshafts by using our welding processes.
