Diesel Camshafts

A worn camshaft affects valve timing, power and fuel economy. Worn lobes, pitted followers and noise from the valve train are common signs. Internet Diesel stocks replacement diesel camshafts for heavy-duty engines.

Camshafts by Engine

We carry camshafts for the Cummins ISX15, ISX, ISM, L10 and N14. We also carry cams for the Caterpillar C7, C9, C10, C12, C13, C15 and 3406E, and the Detroit Diesel Series 60 12.7L and 14L. Some reman camshafts are also offered.

Install Tips

Always inspect or replace the cam followers when you install a new camshaft. Use plenty of assembly lube and follow the break-in steps from the engine maker. If you are rebuilding the whole engine, add a crankshaft and an inframe kit to the same order.

Frequently Asked Questions

Should I replace cam followers too?
Yes. Old followers are worn to the old cam lobes and can damage a new camshaft quickly.

How do I confirm the right camshaft?
Check your engine model, serial number and part number on the old cam, or call us to confirm.
