S&S 4-1/8" Bore Cylinder Set for 124" & 124" Dish Hot Set Up Kits for 2007-'16 Big Twins - Wrinkle Black
S&S 4-1/8" pistons are machined to such close tolerances that it is not necessary to measure the piston. Additionally, the low friction coating on the piston skirt of early production pistons with out micrometer window makes taking measurements very difficult. Therefore, hone cylinders to nominal diameter +/- 0.0001" for correct clearance. Current production pistons have micrometer windows in the coating on the piston skirts that allow accurate measurements to be taken. These pistons may be installed by honing cylinder to nominal diameter +/- 0.0001" or by measuring piston and honing cylinder to achieve .002" - .0025" close clearance for street applications or .0032" - .0045" loose clearance for immediate competition use.
This 4-1/8" bore silver cylinder set has a stock bolt pattern and is 5.004" in length. It is for 124" and 124" Dish Hot Set Up Kits for 2007-'16 big twins.
