About

Unused, uninstalled parts can be returned within 14 days of delivery with prior authorization (see Terms). If you are not sure about a part, please call us before ordering. If you have an issue and need a refund, and you bought directly through Power Stroke Products, we will refund directly to you. If you bought through a dealer, work with them.

If you are sending a camshaft back, pack it properly. Cummins cams are long and brittle — they need to be centered in a 6″×6″×36″ box packed tightly with foam or peanuts all the way around.

Please only have our products installed by qualified professionals wearing proper safety equipment. Make sure safety glasses and gloves are worn when installing valve springs and other dangerous components. Only use quality name-brand valve spring compressors — Snap-on, Mac, Cornwell, OTC, or Craftsman. Do not operate or install components while impaired.

If you are reselling our products, it is your responsibility to pass this information on to your customers.

Our customers use our products in a wide range of applications from 150–3,000hp. There is no way we can engineer a product that will work in every application flawlessly. Modifications, extreme operating conditions and use beyond a component’s limits can cause failure.

We are not responsible for damage from misuse, abuse, mis-matching, over-revving, poor lubrication quality, or any related damage or costs incurred from the failure of our parts. USE AT YOUR OWN RISK. If you are not willing to accept this, please do not buy our products.

If there is an issue with the materials on any of our components, we will at our discretion exchange the flawed components for new pieces. This is the limit of our liability.

Damage caused by inadequate lubrication, overheating, excessive stud tightening or machining through a casting is the customer’s responsibility. Porting/polishing, custom valves, missed dyno time, travel expenses and related costs are not covered.
