Bolt-On Cam Retainer | 5.9L 6.7L Cummins | 1998.5-2018

Bolt-On Cam Gear Retainer for Mechanically Injected Engines

Secure your helical cut cam gear during high RPM, high fuel-delivery situations with our Bolt-On Cam Gear Retainer. Designed for mechanically injected engines, this retainer prevents the gear from being pushed off the cam—especially critical when you’re pushing the limits of your diesel build.

Key Benefits

• Prevent Gear Slippage: Lock your helical cut cam gear in place, even under extreme RPM and fuel delivery.
• Easy Installation: Use red Loctite and torque the bolt to 44 ft-lbs for a reliable hold.
• Compatibility Note:
  • Not Required for Common Rail Engines or any engine with straight-cut (spur) gears.
  • If you use silicone instead of a gasket on the front cover, confirm there’s sufficient clearance between the retainer and cover.

Upgrade to our Bolt-On Cam Gear Retainer and safeguard your mechanically injected Cummins against cam gear push-off, ensuring a stable valvetrain and worry-free performance at high RPM.
