Key Features:

COMP Cams has incorporated advanced design elements into these short travel hydraulic roller lifters to optimize performance and reliability:

• Short travel design reduces lifter movement for quicker valve response and higher RPM capability
• Link bar construction ensures synchronized lifter operation and stability under high loads
• Hydraulic roller mechanism minimizes friction and wear while maintaining precise valve timing
• Light pre-load setting reduces internal stress and improves oil flow efficiency
• Reduced oil volume design enhances engine oil control and reduces parasitic drag
• Durable materials and precision machining for long service life in demanding applications
• Compatible with factory rocker arms and pushrods for straightforward installation
• Sold as a matched pair for balanced valvetrain performance

Construction & Design:

These lifters are crafted from high-quality steel alloys with precision-ground surfaces to ensure smooth operation and durability. The hydraulic roller assembly features hardened rollers and bearings designed to withstand the rigors of high RPM and aggressive cam profiles. The link bar design maintains consistent spacing and alignment between lifters, reducing valvetrain deflection and improving overall stability. The reduced oil volume internal passages optimize lubrication without sacrificing performance, contributing to cooler operation and extended component life.

Installation & Fitment:

The COMP Cams Short Travel Link Bar Hydraulic Roller Lifters are designed as direct-fit replacements for Chrysler 6.4L HEMI engines, requiring no special modifications for installation. They are compatible with factory and aftermarket valvetrain components, making them an excellent upgrade for performance builds. Proper break-in procedures should be followed to ensure optimal hydraulic lifter function and longevity. Installation is straightforward for experienced mechanics and enthusiasts familiar with HEMI engine valvetrain service.
