Fitting a wider 150 series tire to a classic Sportster requires moving the chain line to avoid interference. This off-set sprocket kit from Zodiac provides a 3/16" (5mm) offset, pushing the drive train as far as possible from the tire sidewall. This kit is a perfect fit for 1984–1990 4-speed Sportster models and is engineered to work with 530 series chains. Including both the specialized sprocket and the required spacer, it ensures your final drive remains perfectly aligned even with the increased tire width. It is an essential upgrade for any custom build looking for a more aggressive stance on an early Evolution or late Ironhead Sporty.
