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. 3.927\" .010\" bore.","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":50379028758834,"sku":"SSC106-4416","price":515.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0875\/7365\/9954\/files\/4d8dd4e473f666d68d8b9f855275edacL.jpg?v=1756519106","url":"https:\/\/peterscarparts.com\/products\/s-s-cycle-2007-bt-3-927in-010in-bore-106in-big-bore-forged-pistons","provider":"PETER'S CAR PARTS","version":"1.0","type":"link"}
