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\" standard bore.\u003c\/p\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":47364883054730,"sku":"SSC-106-3690","price":514.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/0619\/2778\/files\/0_a0aa9778fd8ab239a361175d7f1ea674_normalized.jpg?v=1776818307","url":"https:\/\/www.onlyinstock.com\/products\/sands-cycle-106-3690","provider":"Only In Stock","version":"1.0","type":"link"}
