Transmission Retaining Rings

1 products

Our range of Transmission Retaining Rings for Harley-Davidson covers the mainshaft and countershaft bearing retaining rings used in 1999-2026 Big Twin, 2006-2022 XL Sportster and 2008-2012 XR1200 Harley-Davidson transmissions. Iron City Motorcycles in Leeds is an authorised Harley-Davidson dealer, and retaining rings at this level are precision-machined small parts that hold bearings in place against the massive drivetrain forces a Harley-Davidson gearbox sees, where a failed ring allows bearing walk and catastrophic gearbox damage. You will find MCS's workshop-standard transmission retaining rings, manufactured to match the original factory material grade and dimensions used across modern Harley-Davidson Big Twin and Sportster platforms. Whether you are refreshing a Twin Cam Road King, completing a Milwaukee-Eight Touring rebuild or sorting an XL Sportster gearbox service, the correct retaining ring is here.
