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 .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 operationSet of four, with HL2T limited travel kit.

S&S tappets with HL2T Kit require the use of adjustable pushrods. See page 4-19 for S&S adjustable pushrod options. 1984-’99 cams must be used with this kit to ensure correct valve timing. These cams are not included with the kit. Refer to page 5-20 for S&S camshaft recommendations to be used with this kit. If sourcing cams from another manufacturer, note that timing specifications will be unchanged, but the actual lift will be about 9% lower than specified due to the difference in rocker arm ratio. S&S billet tappet guides for shovelhead engines are similar in design to S&S tappet guides for 1984-’99 big twin engines. For that reason, they are not a direct replacement for stock parts, but must be used in conjunction with S&S tappets and cams for 1984-'99 big twin engines. Tappet bore geometry is corrected to compensate for the difference in pushrod angles between the engine types in order to maintain specified valve event timing. When selecting a cam, keep in mind that timing specifications will be the same as shown for 1984-'99 engines, but there will be about a 9% reduction in valve lift due to the lower shovelhead rocker arm ratio. S&S tappets with HL2T Kit require the use of adjustable pushrods. Because of close tolerances, tappets in set part #33-5353 may require slightly longer bleed down time than conventional tappets. At temperatures of 65°F and above, however, bleed-down should take 20 minutes or less using 20W50 engine oil.
