Chevy 348/409 Retro Fit Hyd Roller Lifters

The Chevy 348/409 Retro Fit Hyd Roller Lifters from COMP CAMS are specifically engineered hydraulic roller lifters designed to enhance classic Chevrolet big-block engines. These lifters are ideal for engine builders and enthusiasts looking to upgrade their W-Series GM powerplants with modern roller technology while preserving the original engine architecture.

By converting from flat-tappet to hydraulic roller design, builders benefit from reduced friction, improved valve control, and extended component life. The lifters feature a 0.842-inch outside diameter and utilize a link bar design that ensures synchronized lifter motion, eliminating wear patterns associated with traditional flat-tappet designs. The hydraulic mechanism maintains zero valve lash automatically, reducing noise and accommodating thermal expansion without manual adjustments.

These retrofit lifters are particularly beneficial for restorers and performance builders working with Chevy 348 and 409 cubic-inch engines. Their design allows for seamless integration into existing block and head geometry, making them an excellent choice for those seeking reliability and performance in both street and racing applications.
