Others work better with a heavy pre-load because oil volume is reduced under the plunger which increases lifter stiffness. COMP Cams Short Travel Hydraulic Roller Lifters let you have the advantages of both light pre-load and reduced oil volume producing the most stable and highest-revving hydraulic lifter available. COMP now offers an XD version of these lifters that features a heavy-duty tool Steel Pushrod seat.
