Upgrade your suspension with a Compton fork service on your stock ZRX forks. This service includes 1.0 fork springs, seals, oil, and proper spacers for correct installed preload.
This service helps your forks work great on the street and the track. They allow you to run better chassis geometry that will transform the way your bike handles.
Please allow 2-3 weeks from the time we receive your forks from you.
