MCS Exhaust Gaskets

3 products — part of all Exhaust Gaskets

MCS exhaust gaskets span the full Harley-Davidson model timeline — from 1966 to 1984 Shovelhead applications through 1984 to 2025 Big Twin, 1986 to 2022 XL Sportster, 2008 to 2012 XR1200, and 1987 to 2010 Buell XB — with specific Milwaukee-Eight Softail listings covering 2017 to 2026 (excluding the 2018 to 2021 FXFB and FXFBS Fat Bob, 2018 to 2023 FLSB Sport Glide, and 2019 to 2020 FXDRS models running 2-into-1 exhaust systems), plus 2017 Dyna FXDB and FXDL, 2024 to 2026 FLT/Touring, and 2017 XL883N and 2018 to 2022 all XL Sportster. The exclusions on Softail matter: models with 2-into-1 systems use different port spacing, and MCS lists these separately rather than selling a gasket that won't seal. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries MCS exhaust gaskets through Iron Stable. For a straightforward exhaust service on a Harley-Davidson Big Twin, Sportster, or Shovelhead, the coverage depth here means the right gasket is in stock.
