Valve Collars

6 products

Valve Collars for Harley-Davidson locate the valve spring retainers on the valve stems, ensuring correct spring preload and reliable valve operation. Available from Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, these collars fit Twin Cam, Milwaukee-Eight, Evolution Big Twin and Sportster engines. Jims, Andrews and S&S supply precision-machined steel collars in standard and oversized options that match your specific valve and spring combination. Worn or damaged valve collars can allow the retainer to slip, leading to catastrophic engine damage, so inspecting and replacing them during any valve service is a critical step.
