S&S Hydraulic Tappet Set

S&S Hydraulic Tappets feature numerous significant design improvements and are perfect for stock replacement as well as high performance applications.

• Larger inner bearing race reduces stresses to increase axle, bearing, and roller life. The S&S inner bearing race is .123" larger in diameter than the "raceless" roller axles currently used by some manufacturers.
• Improved inner race-roller design allows use of more, and larger bearings to increase load-carrying surface area, further reducing stress and wear in the critical roller area.
• Redesigned plunger assembly better withstands forces associated with heavy-duty valve springs and cams typically used in high-performance applications.
• Revised metering device precisely controls oil delivery to top end, insuring rapid lifter pump-up and reducing possibility of oil starvation to bottom end.
• Each lifter body and plunger assembly is hand-fit and then pressure-tested to insure correct operation.
• Set of four, without HL2T limited travel kit
• Made in the USA
