Special Order
These short travel retro-fit hydraulic roller lifters feature short travel. This lifter pair's short travel allows for light pre-load and reduced oil volume for the highest revving lifter for Chevrolet Small Block.
When dealing with full travel lifters, certain engines respond better to a light 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 stiffness. COMP Cams(R) Short Travel Hydraulic Roller Lifters allow you to have the advantages of both light pre-load and reduced oil volume, producing the most stable and highest revving hydraulic lifter available. And COMP Cams(R) now offers an XD version of these lifters that feature a billet pushrod seat for added strength and durability in Xtreme Duty applications such as turbo drag cars and offshore powerboats.
