Why Buy the Detroit Diesel 3-71 Non-Turbo 4-Valve Head Camshaft from Diesel Pro Power

The Detroit Diesel 3-71 non-turbo engine with a 4-valve head relies on precise valve timing to achieve optimal airflow, fuel efficiency, and smooth power delivery. The camshaft is the key to maintaining that precision, ensuring each valve opens and closes at exactly the right moment. Over time, wear on cam lobes or bearings can lead to performance loss, rough idle, or reduced fuel economy — clear signs that replacement is needed. For a high-quality, direct-fit solution, Diesel Pro Power offers premium camshafts built specifically for the 3-71 4-valve configuration.

Each camshaft from Diesel Pro Power is manufactured or reconditioned to OEM-level specifications, with exact lobe profiles and journal diameters to ensure perfect timing and smooth operation. Hardened surfaces resist wear even under continuous load, while tight machining tolerances guarantee consistent valve lift and duration. These camshafts restore full performance and protect against premature wear in pushrods, rockers, and valves.

Beyond the part itself, Diesel Pro Power offers everything needed for a complete top-end rebuild — from bearings, bushings, and gaskets to related valve train components.
