530 Harley Rear Sprocket - ProSeries - Standard Designs

*This listing includes a CUSTOM MADE TO ORDER rear sprocket that generally ships in 1-3 days for Circle Hole Design or Solid Design(with no holes).

All ProSeries Sprockets are Made in the USA from the harder grade 7075-T6 certified aero space industry aluminum for long life and light weight. They are machined to exact specs with tolerances much more stringent than other aluminum sprockets and many times tighter than OE sprockets. What this means is that your chain will fit the sprocket better and everything will last longer.

Additionally, they are chemically etched to give them a uniform, even finish. This process also provides corrosion resistance.

The lightweight parts and low friction chain will improve your HP 5 to 7 percent at the rear wheel.

Important Notes-

-All existing chains should be checked for wear (stretched, binding, tight spots, etc.) before new sprockets are installed. Installing new sprockets on a worn chain will significantly reduce the sprocket life and can cause serious damage.

-The chain tension on all modern sport bikes should be maintained with a minimum of 2" of top-to-botom travel to accommodate full suspension movement and prevent premature chain stretching and sprocket wear.
