About This Product
For the Milwaukee-Eight owners, this Arlen Ness Knuckle Stage 1 Big Sucker kit is engineered to solve the common oil blow-by issues while boosting performance. It features a chrome finish and a high-flow cotton gauze filter pre-oiled with black oil. The patent-pending hidden breather system uses proprietary shooter tubes to pass oil through the backing plate and into the mouth of the throttle body, supported by an integrated oil catch reservoir. It is a clean, one-piece aluminum design that really opens up the intake. This kit fits 2018 to 2024 Softail models, 2017 to 2025 Touring models excluding 2024-up Street Glide and Road Glide models and specific CVO variants, and 2017 to 2025 Trike models.
Manufacturer part number: 18-393.
