These air shafts are new, but not new at the same time. These were removed from brand new forks and have never been used. We change the travel on Fox forks free of charge for customers who request a travel that Fox does not offer from the factory, so we often have some leftover air shafts from these travel changes. If you&';re looking to change the travel either up or down in your 2026+ Fox Float 36 fork, or upgrade to the NA3 Glidecore air spring in your 2021+ Fox Float 36 fork, then just snag an air shaft and swap it out in your fork! Fits 2021+ Fox 36 Factory, Performance Elite and Performance forks. Does not fit Fox 36 Rhythm. Sold as-is with no manufacturer warranty, includes both crush washers required to re-install fork lowers. Foot nut not included.
