Weight 143 grams each. Jims Powerglide™ tappets will give you a superior hydraulic function when compared with OEM style equipment; a billet steel body with hand-honed hydraulic unitcavity and an oil fed axle. To get full power; you must have zero valve lash and eliminate collapsing of the hydraulic unit as is found in the OEM unit; also called ''the shock absorber syndrome''. Failing to keep the valve open the full amount results in power loss. The Jims Powerglide tappets come as close to a solid tappet as possible; but are still able to compensate for heat expansion. They will even work well with solid style camshafts. Fits as an oversized improved replacement for OEM 18526-89.   Note: Standard diameter is .9035\".\u003c\/p\u003e","brand":"Jims","offers":[{"title":"Default Title","offer_id":52729192382792,"sku":"978109","price":206.9,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/holydeath.com\/fr\/products\/jims-powerglide-hydraulic-tappet-001-o-s-1","provider":"Holy Death Motorcycle Co.","version":"1.0","type":"link"}
