Primary Housing Offset Spacers

3 products

Our range of primary housing offset spacers for Harley-Davidson covers precision spacers used when fitting wider rear tyres or aftermarket pulleys that require the primary to be moved outboard. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks primary housing offset spacers from Belt Drives Ltd. — the long-established American specialist whose primary and belt drive components are used widely across the Harley-Davidson custom and performance scene. Fitment covers 1970–2006 Big Twin (excluding 2006 6-speed Dyna), so this part suits late-Shovelhead, Evolution and Twin Cam Big Twin platforms commonly fitted with wider rear tyres. Offset spacers are essential when you've fitted a wide-tyre kit or open belt primary that pushes the rear sprocket alignment outboard — the spacer keeps your primary chain or belt running true.
