{"product_id":"jims-powerglide-steady-roll-tappet-002-o-d","title":"JIMS, Powerglide Steady Roll tappet +.002\" O.D","description":"\u003cp\u003eThis is the Powerglide with a failsafe solid bronze alloy bushing instead of a regular roller bearing. No other differences excist between the regular Powerglide and the Powerglide Steady Roll tappets. Full bearing contact provides more stability; longer life and quieter operation due to the tighter tolerances this bushing design allows. The major drawback of a worn needle bearing roller is they will eventually break; spilling steel needles throughout your engine. This is no longer an issue. Even when the Steady Roll bronze bushing wears out the design is failsafe. Like the other Jims Powerglide™ tappets this Steady Roll version 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 upgraded replacement for OEM 18538-99C Standard and 17900022A High Capacity.  Note: Standard O.D. is .8420\"\u003c\/p\u003e","brand":"Jims","offers":[{"title":"84-99 Evo Big Twin; 86-90 XL Sportster; 87-90 Buell","offer_id":45133762265157,"sku":"978620","price":799.0,"currency_code":"AED","in_stock":true},{"title":"99-17 Twin Cam; 17-26 M8; 00-22 XL Sportster; 08-12 XR1200; 00-10 Buell XB","offer_id":45133762297925,"sku":"978623","price":999.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/4103\/9685\/files\/978620k_5674d6d3-a711-4104-8f6b-f9a8145661cf.jpg?v=1781173752","url":"https:\/\/clubstyledubai.com\/products\/jims-powerglide-steady-roll-tappet-002-o-d","provider":"Clubstyle Dubai","version":"1.0","type":"link"}
