Chrome/molybdenum spare piston set of S&S.
It adapts to all Super Sidewinder S&S with 4 "interior diameter (including TC).
Interior diameter of the standard cylinder: 4.00 "(101.60 mm).
Note the separation of the compression segment: it is very important to determine the correct separation of the segment in the newly installed piston segments.
A space too narrow can result in premature wear of the piston/cylinder wall or even in grabbing, possibly breaking the rings and/or damaging the pistons and/or the walls of the cylinder, etc.
A separation of the piston segment that is wider than necessary will result in unnecessary compression loss and a reduction in engine efficiency.
The recommended separation between rings is 0.004 "per inch diameter of the cylinder for street engines.
For an interior diameter of 3-5/8 "(3,625"), the separation between engine piston rings would be 3,625 "x 0.004" = 0.0145 ". (0.0145" x 25.4 = 0.3683 mm or, when rounded, 0.37 mm).
