Note: Will not work as bolt-in with OEM H-D 4" big bore conversion cylinders in OEM 96" & 103" crankcases. The cylinders will hit a small step in the crankcase. Also clearance between piston skirt and crankcase must be checked at bottom dead center. Cases with a large cast-in bump; just below the machined area for the cylinder sleeve; must be machined for adequate piston skirt to crankcase clearance. This is on both front & rear cylinder exhaust sides of the crankcase. Note: Will not fit 110" CVO models. Note: All KB forged pistons come equipped with offset wrist pins / piston pins. There is a front and rear section on the piston and it is necessary to install it in the correct way. Please refer to the installation instructions; as provided with each piston set; prior to installation.
