Stock cylinders may be bored to accomodate larger pistons, but we recommend S\u0026amp;S 3.927\" bore cylinders which feature high strength alloyed cast iron liners. Pistons are compatible with stock rods with tapered wristpin ends. S\u0026amp;S® 3.927\" bore pistons are machined to such close tolerances that it is not necessary to measure the piston. Just bore cylinders to nominal diameter +\/- 0.0005\" for correct clearance. Additionally, the low friction coating on the piston skirt makes taking measurements very difficult. 3.937\" standard bore.","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":44916299137210,"sku":"SSC920-0100","price":499.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/0855\/6218\/files\/a4800e09e3c58c2ade186d2aa5538788L.jpg?v=1772574381","url":"https:\/\/performancemods.com\/products\/s-s-cycle-2007-bt-3-937in-x-4-3-8in-piston-set","provider":"PERFORMANCE MODS","version":"1.0","type":"link"}
