2003–2018 5.9L and 6.7L Cummins OEM Replacement Camshaft
This camshaft retains the original lift and duration at .050-inch lift for stock performance. It is listed for 2003–2018 5.9L and 6.7L Cummins engines.
Required lifters
Use Hamilton Cams 1.45-inch lifters with this camshaft. Confirm vehicle fitment and follow the oil and warranty requirements below.
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.
For 2003–2018 5.9L and 6.7L Cummins engines needing stock cam timing, this replacement keeps the original lift and duration at .050-inch lift. It requires Hamilton Cams 1.45-inch lifters; follow the oil requirements below.
