The Fox Seal Kit: 34 FLOAT NA2 Rebuild restores the air spring seals in Fox 34mm forks from model year 2016 onward. This kit contains the wiper seals, O-rings, and backup rings needed to refresh the FLOAT NA2 air spring assembly, helping riders maintain smooth travel and consistent air pressure retention after regular trail use.
Fox recommends a full air spring service every 125 hours of riding to keep the FLOAT NA2 system performing as intended. During rebuild, the air side bore measures 1.214 inches with a 1.208 inch piston, and bath oil volume depends on travel length: shorter travel forks use more fluid than longer travel models.
