Professional Installation and Tuning Required

This is a performance engine component package intended for installation by a qualified engine builder, certified machinist, or technician experienced with 6.4L HEMI valvetrain and variable cam timing systems.

A compatible phaser limiter or phaser lock is required. Engine calibration may also be necessary after installation to properly accommodate the altered camshaft profile and related engine operating characteristics.

Recommended Inspection Procedures

• Inspect the camshaft bearings before installing the replacement camshaft.
• Inspect the rocker arms, rocker shafts, pushrods, and related valvetrain components.
• Verify valve-to-piston clearance for the specific engine combination.
• Verify pushrod length and valvetrain geometry during assembly.
• Inspect the timing chain, guides, tensioner, and sprockets.
• Confirm the correct phaser limiter or phaser lock before final assembly.
• Check the cylinder heads for cracks, warpage, and damaged sealing surfaces.
• Clean all engine oil passages and internal surfaces thoroughly.
• Remove all metallic debris from any previous camshaft or lifter failure.
• Prime the lubrication system before initial startup.
• Verify proper engine oil pressure before returning the vehicle to service.
• Follow the COMP Cams installation instructions and factory torque procedures.
• Use new engine oil and a new oil filter after assembly.

Fitment Notice

Exact compatibility depends on the vehicle year, VIN, engine configuration, cylinder head configuration, lifter system, variable cam timing system, engine modifications, and calibration. Vehicle model and year alone do not guarantee fitment.

Performance Component Notice

Actual horsepower, torque, idle quality, drivability, and operating characteristics depend on the complete engine combination, exhaust system, intake system, compression ratio, drivetrain, tuning, and installation quality. No specific power gain is guaranteed.

Warranty Information

The stated lifetime warranty applies when the kit is installed by a certified machinist and remains subject to the manufacturer’s complete warranty requirements. Proof of qualifying installation may be required.

Warranty coverage may not apply to damage caused by improper installation, incorrect tuning, inadequate lubrication, insufficient piston-to-valve clearance, incorrect valvetrain geometry, contaminated oil passages, improper phaser control, overheating, or failure to correct the original cause of engine damage.
