About This Product
The Arlen Ness 10-Gauge Stage 1 Big Sucker is designed to deliver maximum airflow velocity for the latest generation of Harleys. This kit features a black anodized billet outer cover and a pre-oiled high-flow filter element. The backing plate includes an integrated smooth radius air inlet and venturi to pull air efficiently into the throttle body, resulting in improved horsepower and torque across the entire RPM range. It is a clean, bolt-on installation that fits 2025 to 2026 Softail models and 2024 to 2026 Street Glide and Road Glide models, including CVO and STSE editions. The filter ring design neatly covers the urethane edge for a professional, finished look.
Manufacturer part number: 600-307.
