-> Forged to be harder than OEM requirements (up to 55 Rockwell C), which makes it more resistant to wear and fatigue when it runs for a long time.

• Ideal for heavy-duty trucks, motorcoaches, and vocational vehicles from 2001-2010 era, where ISX power ranges from 430-620 HP.​

• Cross-references popular aftermarket numbers like PAI 191817, ensuring easy sourcing without modifications.

Usage:

-> Keeps the timing tolerances (±0.003″ to ±0.006″ for important CM871 applications) accurate, which makes the engine work better and stops problems like white smoke or oil filter clogging.

-> This product is designed to last in marine, oil and gas, and off-highway applications, delivering torque up to 2050 lb-ft, which is better than typical replacements.

-> Supports the Cummins Interact System (IS) for full-authority fuel regulation, which increases power output while still meeting emissions criteria.
