1998–2002 5.9L Cummins OEM Replacement Camshaft

This replacement follows the factory cam profile and is intended to retain stock performance. It uses a wider lobe than the original design.

Use the vehicle-fitment listing to confirm your application. If you are choosing between a stock replacement and a performance grind, contact us with your engine year and intended use.

Approved oil — required. Use a 15W-40 (or 5W-40 in sub-zero conditions) with adequate zinc, phosphorus, and molybdenum. Thin or low-additive oils don’t provide the shear strength a flat tappet needs. Approved oils:

Valvoline Full Synthetic 15W-40
Valvoline Synthetic Blend 15W-40
Valvoline All-Terrain 15W-40
Schaeffer’s 15W-40
Mobil Delvac Extreme 15W-40
LIQUI MOLY Touring High Tech 15W-40
Driven Racing Oil 15W-40
Redline 15W-40

Acceptable:

Shell Rotella T6 Full Synthetic 15W-40
Shell Rotella T5 15W-40

Preferred filter: Fleetguard Stratapore LF16035. Running a non-approved oil voids the warranty. All warranty claims must include the failed parts and an oil sample.
