Lifters Bbc Retro-Fit Hydraulic Roller Xd

Description

Certain engines respond better to a light lifter pre-load because it recovers more quickly from any bad harmonics in the valve train. 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. This adds strength and durability in Xtreme Duty Applications such as turbo drag cars and offshore powerboats. The lifters are available for a variety of Chevrolet, GM LS and Chrysler engines.
