Description
Lifter noise and premature wear are common issues in high-performance engines, often traced back to improper lifter rotation and excessive clearance. The Feuling Oil Pump Corp. Anti-Rotation Lifter Pins 4100 eliminate both problems with precision engineering and tight tolerances, keeping your valvetrain quiet and extending component life under sustained boost or RPM loads.
These CNC-machined pins maintain the exacting 0.002″ to 0.003″ clearance specification required for noise-free operation while preventing lifter spinning that accelerates wear. Installation is straightforward and bolt-on, making them an essential upgrade for any serious engine build or rebuild.
