Product information

Overview

Product Overview

S&S Cycle 55-1593 is a two-pack of weld-in mounting bosses used to add oxygen-sensor ports to motorcycle exhaust head pipes.

Verified Specifications

  • Manufacturer part number: 55-1593
  • Product role: Oxygen-sensor mounting boss
  • Installation: Trace the boss profile, prepare the head pipe and weld the boss in place
  • Package: Two mounting bosses

Fitment and Installation

S&S installation guidance positions oxygen sensors approximately 4–12 inches from the exhaust flange. On a stock rear FLT head pipe with a Y-section, locate the right-side sensor at least 3 inches downstream of the Y. Final placement depends on the exhaust system and sensor clearance; professional exhaust fabrication is required.

Before ordering

Confirm the exhaust-pipe and sensor mounting requirements with the installer before ordering.
