S&S Piston cooling jet kit

Twin Cam style engines with strokes longer than stock, require special piston cooling jets to avoid contact with pistons at the bottom of the stroke. S&S cooling jets provide an extra .150" of clearance between the jet and piston skirt compared with stock jets. These special jets are included in the S&S 107" and 116" Sidewinder and Hot Set Up kits. S&S piston cooling jets are sold in kits.
