They also are used in S\u0026amp;S\u003csup\u003e®\u003c\/sup\u003e engines for 1966\u0026amp;-'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\u0026amp;S\u003csup\u003e®\u003c\/sup\u003e 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, with HL2T limited travel kit.\u003c\/p\u003e \u003ca href=\"https:\/\/www.sscycle.com\/content\/document_center\/Instruction_Sheets\/51-1040_hydraulictappet_20060427.pdf\" target=\"_blank\" alt=\"Download Instructions\"\u003eInstall Instructions Download\u003c\/a\u003e\u003ca href=\"https:\/\/www.sscycle.com\/content\/document_center\/Instruction_Sheets\/106-6046-adjustable-pushrods.pdf\" target=\"_blank\" alt=\"Download Additional Instructions\"\u003eAdditional Install Instructions\u003c\/a\u003e\u003ch3\u003eFITMENT DISCLAIMER\u003c\/h3\u003e\n\u003cp\u003eFitment information is provided as a general reference only and is not guaranteed for any motorcycle, whether stock or modified.
