Good To Know

Q: How do I know if this is the large or small spring? A: This listing is for the large spring, so measure the bellow seat and compare with your original before ordering. Some assemblies use two different spring sizes.

Q: Can I replace just the spring? A: Yes, the spring can be serviced on its own, though many riders replace the bellow at the same time if it shows wear or cracking.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
