The main reason for changing the firing order with the camshaft is to relieve stress on the front portion of the crankshaft. The OEM firing order ends with cylinder #3 and begins with cylinders #1 and #2. Duramax engine crankshafts have a tendency to break right behind the first rod throw at the intersection of the second main journal. With a Wagler Competition alternate firing camshaft, cylinders 1, 2, and 3 are moved away from each other to help extend the abuse the crankshaft can withstand.

Features:

  • No piston valve reliefs needed
  • Great replacement for tow, street & mild race
  • Relieves crankshaft stress
  • Reduces chances of broken crankshaft and costly repairs
  • Simple wiring pin swap, no major modifications needed

Includes:

  • Stage 1 alternate firing camshaft

Notes:

  • Engine wiring harness modifications are required due to the new firing order
