Red S&S Sprocket for Harley-Davidson

Note: All S&S pinion shaft gears are designed for use with a BT 73-99 style 24 tooth driven gear (OEM 26345-73 / MCS 531209 S&S).

The color coding sequence is identical to the standard HD encoding.

When in doubt, use a gear from the mid to small range.

A combination of smaller gears should provide adequate clearance under most circumstances.

Both excessive and zero gear combinations cause engine noise, but insufficient backlash causes binding and premature wear.
