Upgrade your Cummins valvetrain with our premium cam bearings, engineered to withstand higher pressures and extended RPM use. Ideal for replacing worn or damaged OEM bearings, these made-in-the-USA components provide long-lasting durability in both stock and performance builds.

• Durable Construction: Perfect for engines running over 450 lbs of nose pressure or steel camshafts.
• Versatile Fit:
  • 12V Engines: One bearing on the first journal.
  • Some Common Rail Engines: One bearing on the first journal and one on the seventh.
  • For extreme builds, machine your block to run bearings on all seven journals.
• Two Size Options:
  • HC-1: For stock-size cam journals (2.124″ diameter).
• Precise Bore Requirement: Both HC-1 and HC-2 bearings require a 2.333″ (+/− 0.0005″) cam bore.
