Welcome to Allens Crankshafts Ltd!

We specialise in producing crankshafts machined from solid steel billet, cast or forged material using the latest Mori Seiki multi axis CNC machines – ensuring all our products are manufactured to the highest customer requirements. We use EN40B steel and it is supplied by Hillfoot Steel.

Do you need a special one off crankshaft?

We offer a full design, development and manufacturing service to help you complete your special engine build or restoration project. Your design can start with either a pattern in the form of an original component or we can work from drawings.

All the crankshafts we manufacture are fully stress relieved.

Con Rods

Complement your new crankshaft with a new set of con rods.

We stock a wide range of con rods by Saenz and can source them to your specification.
