Excessive valve thrust and valvetrain wear drove S\u0026amp;S engineers to design stronger, more durable components that will help you get the most out of your M8. S\u0026amp;S Forged Roller Rocker arms for M8 models are stronger, more durable and easier on the rest of your valvetrain, and are essential for increasing the longevity of your valvetrain components on cams with greater than .550\" lift. \u003c\/p\u003e \u003cstrong\u003eFEATURES \u0026amp; BENEFITS\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eForged from 8620 steel for greater strength\u003c\/li\u003e\n\u003cli\u003eDesigned using Finite Element Analysis (FEA)\u003c\/li\u003e\n\u003cli\u003eRollers eliminate thrusting on valves for decreased wear on the valve train\u003c\/li\u003e\n\u003cli\u003eRocker geometry is better suited to high lift cams\u003c\/li\u003e\n\u003cli\u003eBushings are 50% longer than stock, increasing time between rebuilds\u003c\/li\u003e\n\u003cli\u003eLarger surface area on the thrust surfaces reduces wear on the heads\u003c\/li\u003e\n\u003cli\u003eOil is sprayed directly on the valve springs, reducing potential for breaking a valve due to over-heating (stock rockers tend to oil the rocker boxes, not the valves)\u003c\/li\u003e\n\u003cli\u003eCompatible with stock or S\u0026amp;S CNC heads\u003c\/li\u003e\n\u003cli\u003e1.640 Ratio\u003c\/li\u003e\n\u003cli\u003eCapable of .650\" max Valve Lift\u003c\/li\u003e\n\u003cli\u003eServiceable and rebuildable for generations of durabilty\u003c\/li\u003e\n\u003cli\u003eA must have for cams with .550\" or greater lift!\u003c\/li\u003e\n\u003c\/ul\u003e \u003ca href=\"https:\/\/www.sscycle.com\/content\/document_center\/Instruction_Sheets\/510-0737a-m8-rocker-assembly.pdf\" target=\"_blank\" alt=\"Download Instructions\"\u003eInstall Instructions Download\u003c\/a\u003e\u003cbr\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.
