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. \u003cbr\u003e\u003cbr\u003ePart Number : 920-0101 \u003cbr\u003e\u003cbr\u003e920-0101 \u003cbr\u003e\u003cbr\u003e     These big bore pistons work with the stock 4\" stroke flywheels to convert any 1999-'06 HD® big twin engine from 88\" to 98\" displacement with 10.3:1 compression with stock heads.
