36 Air Shaft Assembly - 2026, 140mm, FLOAT NA 3, 1.287" Bore, Two-Piece Neg Plate

Fox 36 Air Shaft Assembly is a direct-replacement air-spring shaft for servicing or reconfiguring compatible Fox 36 FLOAT suspension forks that use a 1.287" air-spring bore. Spec’d in 2026 trim with FLOAT NA 3 architecture, this assembly is the core part that sets fork travel and restores correct air-spring function when rebuilding a worn or damaged air spring.

• 140mm Travel Configuration - Replaces the air shaft to restore or set a 140mm travel setup where the fork chassis/air-spring platform supports that travel
• FLOAT NA 3 Design - Matches the intended air-spring layout for 2026-era compatible Fox 36 FLOAT forks to maintain correct spring behavior and serviceability
• 1.287" Bore Compatibility - Built for Fox 36 air-spring systems using the 1.287" bore size; critical for proper fit and sealing
• Two-Piece Negative Plate - Uses the specified two-piece negative plate design for the correct internal spring layout on compatible forks
• Service-Ready Replacement - Ideal for air-spring overhauls when addressing wear, contamination, or damage inside the air-spring assembly

Compatibility is determined by fork model year, air-spring type, and bore size; verify the fork’s Fox 36 air-spring specifications before ordering.
