They are machined to a higher standard to provide significantly lower leak down rates for quick pump up, consistent quiet operation, and stability at high rpm. They also feature a low mass, bearing grade, silicon nitride check ball and a lighter ball spring, which allows these tappets to operate efficiently on less oil pressure. That means they pump up quickly and stay quiet from start-up to the end of the ride, even with high oil temperatures. Thanks to the close machining tolerances and low leak down rates they also handle high lift cams and stronger, performance valve springs with ease, extending the usable rpm range of your engine. Precise top end oil metering delivers just the right amount of oil to the rocker arms. This avoids leaks and oil carry over from too much oil, as well as premature rocker and valve wear from insufficient oil supply. S&S Premium High Performance Tappets are available with or without the S&S HL2T limited travel kit installed. With the close tolerance and low leak down rate of these lifters, the main benefit of the limited travel kit is to improve starting for engines not equipped with S&S Easy Start Cams. Sold in sets of four only. Fitment • 1999-Up Big Twins • 2000-Up sportsters Features • 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, silicon nitride check ball and lighter check ball spring - enhances fast pump up and quiet operation • 100% tested to ensure that leak down and top end oil flow are within specification JIMS® BILLET 7075-T651 TAPPET BLOCKS Tappet Blocks are designed to accomodate a gross valve lift of .550” at the valves. This is about .350” at the tappets, leaving a clearance of .035” roller to block freeplay. Any cam over .550” lift needs to be checked and should have .035” to .045” roller to block clearance (Please note, if using a cam with a higher lift, a simple modification to tappet blocks is all that is needed).
