COMP Cams short travel XD hydraulic roller lifters offer the advantages of both light pre-load and reduced oil volume, producing the most stable and highest-revving hydraulic lifter available. The XD versions feature heavy-duty tool steel pushrod seats. This adds strength and durability in extreme-duty applications, such as turbo drag cars and offshore powerboats. Certain engines respond better to a light lifter pre-load because it recovers more quickly from any bad harmonics in the valvetrain. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases lifter stiffness. Now you have the best of both—with COMP Cams short travel XD hydraulic roller lifters. Order the model designed for your vehicle and engine application.
