Facts
Description
  • Cylinder pair by S&S
  • fits Evolution Big Twin
  • aluminum, bare
  • nominal bore: 3-1/2 ”
  • inner Ø: 88.67 mm
  • USA
  • gross weight: 12.8 kg

Stock 3-1/2” bore cylinders by S&S made as strong as the famous Sidewinder big bore cylinders. Can be used as stock replacement for Evolution models and feature additional fin surface for improved heat dissipation and rigid casting for more reliable gasket seal. Oil return passages are stock for simple installation. We strongly recommend these jugs for stroker engines.

Unlike stock cylinders S&S Evolution style front and rear cylinders are different. So watch their respective position during installation.

Cylinders which are not offered as complete kits, i.e. with pistons and rings, are not finish honed. This job must be performed in a qualified workshop.
