The Mopar Hi-Tech Roller Lifter 383-440 426 by COMP CAMS is a precision hydraulic roller lifter designed for big-block Chrysler engines, providing reliable valve train performance for enthusiasts and shops. These lifters are ideal for those rebuilding or upgrading classic muscle cars, replacing stock components with modern roller technology that reduces friction and wear while maintaining OEM valve geometry.
Roller lifters operate using a precision-machined roller on the lifter body that rides the cam lobe, which minimizes friction losses and allows for quicker valve operation without sacrificing durability. This design is particularly beneficial when using aggressive cam profiles or running at higher RPMs. The construction of COMP CAMS roller lifters includes high-quality materials and tight tolerances to ensure consistent lifter preload and eliminate unwanted lash.
These lifters are essential for anyone looking to enhance the performance of their 383, 440, or 426 Hemi engine, delivering the reliability that both street and strip builders demand. Installation requires a complete set of lifters, and proper pushrod adjustment is necessary for optimal performance.
