Pulleys Offset And Nut Kits

3 products

Our range of pulley offset and nut kits for Harley-Davidson covers matched offset pulley and nut combinations for custom and wide-tyre Big Twin builds. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks offset pulley and nut kits from Belt Drives Ltd. — the long-running American specialist whose drive components are used widely across the Harley-Davidson scene. These kits are aimed at builders refitting wider rear tyres or aftermarket wheels on Softail, Dyna, FXR and similar platforms, where a stock pulley would put the belt out of alignment. The kit pairs a correctly machined offset pulley with the matched retaining nut, so you avoid the guesswork of stacking individual parts and chasing torque values. Whether you're building a Pro Street-style Softail, a wide-tyre Dyna chopper or an FXR custom, fitting the right offset combination keeps the belt running straight and the drive happy.
