Construction & Design:
COMP Cams lifters are manufactured with precision-machined components and high-quality materials to ensure consistent performance and durability. The short travel design reduces the lifter’s internal oil volume, which decreases hydraulic lash and allows the lifter to respond quicker at high RPMs. This design also minimizes valvetrain deflection and wear, contributing to longer service life under demanding conditions.
The non-link bar style maintains OE compatibility, making installation straightforward without requiring extensive valvetrain modifications. Each lifter is engineered to meet strict quality 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 compatible vehicles equipped with the 6.4L HEMI engine. Installation requires standard engine disassembly procedures and should be performed by a qualified technician familiar with valvetrain components. No special modifications are necessary, and the lifters fit seamlessly into the OE-style valvetrain setup.
Proper preload adjustment is critical to maximize performance and longevity, and the short travel design facilitates easier and more precise preload settings. Always refer to COMP Cams installation instructions and vehicle service manuals for detailed guidance.
