Construction & Design

COMP Cams lifters are manufactured using precision-machined components and premium materials to ensure consistent performance and long-lasting durability. The short travel design minimizes the lifter’s internal oil volume, reducing hydraulic lash and allowing the lifter to respond more rapidly at elevated RPMs. This also helps to minimize valvetrain deflection and wear, extending service life under high-stress operating conditions.

The non-link bar style preserves OE compatibility, enabling straightforward installation without the need for extensive valvetrain modifications. Each lifter undergoes rigorous quality control to meet strict standards, ensuring reliable operation in both street and performance environments.

Installation & Fitment

These hydraulic roller lifters are designed as direct replacements for factory lifters in vehicles equipped with the 6.4L 392 HEMI engine. Installation follows standard engine disassembly procedures and should be performed by a qualified technician experienced with valvetrain components. No special modifications are required, and the lifters integrate seamlessly into the OE-style valvetrain setup.

Proper preload adjustment is essential to maximize performance and durability. The short travel design facilitates easier and more precise preload settings. Always consult COMP Cams installation instructions and the vehicle’s service manual for detailed guidance.
