The COMP Cams short-travel hydraulic roller lifter is a drop-in OE-style unit for late-model Chrysler Gen III 6.4L HEMI engines. It features reduced travel for lighter preload and lower oil volume to support higher revving operation. Not compatible with MDS; if converting from MDS you must replace MDS lifter yokes with COMP Part #8561-1. Pushrod seat height is approximately .100" shorter than OE.
