Pulleys Transmission Spacers

1 products

Our range of pulleys transmission spacers for Harley-Davidson covers precision spacers used to fine-tune front-pulley position on belt-drive Big Twin and Sportster fitments. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks transmission pulley spacers from MCS — a long-established Harley-Davidson aftermarket supplier. Fitment covers 1985–early-1994 5-speed Big Twin and 1991–1994 XL Sportster, both belt-drive platforms where small adjustments to pulley position can correct belt tracking issues. Whether the alignment has drifted after a transmission rebuild, or you've installed a non-stock rear pulley that needs a small front-end correction, transmission pulley spacers give you the millimetre-scale adjustment needed to bring the belt back into line. Belt drive systems are unforgiving of misalignment, so having the correct spacer thickness on hand during a primary or final drive service is a smart move. Browse the full range below.
