Cummins Camshaft
Description

178/204 Camshaft (105.5 LSA) – Gain 25–35 HP with OEM Pushrods

Experience a noticeable boost in power and efficiency without overhauling your entire valvetrain. Our 178/204 Camshaft(on a 105.5 LSA) delivers 25–35 horsepower gains, lower EGTs, and quicker turbo spool—all while running on OEM pushrods for ultimate convenience.


Camshaft Specs

  • Intake: 178° @ .050″ duration / .270″ lift
  • Exhaust: 204° @ .050″ duration / .310″ lift
  • Lobe Separation Angle (LSA): 105.5°

Key Benefits

  • Immediate Power Increase: See a reliable 25–35 HP bump, verified in real-world testing.
  • Lower EGTs: Keep engine temperatures in check for enhanced longevity and performance.
  • Faster Spool-Up: Get on boost sooner for more responsive throttle control.
  • OEM-Friendly: Retains stock pushrods—no major additional valvetrain upgrades required.

Coming Soon: Solid Lifter Conversion Kit

For those looking to push even further, stay tuned for our Solid Lifter Conversion Kit, including upgraded pushrods, rocker arms, and bridges. Unlock even greater potential and durability when you combine this cam with our upcoming performance package.


Upgrade to the 178/204 Camshaft and enjoy the sweet spot of practical power gains, improved drivability, and valvetrain simplicity.
