COMP Cams Lifters Retro-Fit Short Travel Hydraulic Roller - 1997-16 GM LS Series - 15956XD-2

XD Short Travel Link Bar Hydraulic Roller Lifter Pair GM LS, LSX, RHS, Warhawk

These short travel retro-fit XD hydraulic roller lifters feature a billet seat and short travel. This lifter pair's short travel allows for light pre-load and reduced oil for the highest revving lifter for factory, RHS, LSX and Warhawk LS.

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 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 now offers an XD version of these lifters that feature a a billet pushrod seat for added strength and durability in Xtreme Duty applications such as turbo drag cars and offshore powerboats.
