    Product Details

    High Performance Hydraulic Tappets (33-5353) by S&S Cycle®. Reduced valve train noise from start up to shut down.Close tolerances for low leak down rates; fast pump up and superior high-RPM performance. Low mass, bearing grade, silicone nitrate check ball and lighter check ball spring; enhances fast pump up and quiet operation. S&S® Hydraulic Tappets fit all HD® Evolution®, HD® big twin engines and 1986-'90 Sportster® models. They also are used in S&S® engines for 1966&-'84 big twin chassis. These tappets feature numerous significant design improvements and are perfect for stock replacement as well as high performance applications.Features and Benefits: Larger inner bearing race reduces stresses to increase axle, bearing, and roller life: the S&S® inner bearing race is 0.123 larger in diameter than the raceless roller axles currently used by some manufacturers.

    Installation

    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, with HL2T limited travel kit.
