OEM Harley Knucklehead Panhead Shovelhead 4 Speed Mainshaft Shift Clutch 35440-38

Description

Original Equipment Manufacturer (OEM) Harley-Davidson Big Twin 4-Speed Transmission Mainshaft 3rd & 4th Gear Shifter Clutch Slider.
  • Part Number References: OEM #35440-38 / #35440-38T
  • Authenticity Marking: Features the crisp, factory-original "HIGH" stamping on the outer slider dog collar profile. [1, 2]
Up for sale is a genuine vintage factory Harley-Davidson 4-speed transmission internal 3rd/4th gear mainshaft shifter clutch gear takeoff. Removed directly from a classic Big Twin manual gearbox assembly, this is an authentic US-made high-tensile hardened steel internal component. It features the classic 4-lug external face-locking dog profile and deep internal spline tracking paths. [1, 2, 3]
Avoid cheap unbranded reproduction shifting collars that warp or drop out of spec under load, causing your vintage bike to dangerously pop out of 3rd or 4th gear under heavy acceleration. This factory original hardened steel piece provides the exact structural spacing and dog alignment parallelism required to restore crisp shifting mechanics and rock-solid high-gear lockup. It is an essential mechanical asset for anyone overhauling an early Knucklehead, Panhead, or Shovelhead chopper, building a vintage bobber project, or restoring a classic ratchet-top/rotary-top gearbox assembly. [1, 2]

šŸļø Fitment & Vehicle Compatibility:
Direct factory drop-in application for standard 4-speed manual gearboxes across the classic Big Twin generations: [1]
  • Harley-Davidson Knucklehead / Panhead / Shovelhead: Fits 1937 to 1985 EL, FL, FLH Electra Glide platforms, and 1971 to 1985 FX, FXE Super Glide, FXS Low Rider, and FXWG Wide Glide configurations running a standard 4-speed mainshaft layout. [1]

šŸ” Condition Notes:
This is a pre-owned vintage factory transmission takeoff component.
  • Shifting Dogs: The 4 outer face-locking engagement dogs and internal slider teeth are structurally solid, true, and free of severe rounded profiles, edge gouges, or deep back-cut wear from missed shifts. [1]
  • Internal Splines: The internal tracking spline teeth are clean, sharp, and entirely free from step-wear wallowing or twist deformation. [1]
  • Cosmetics: The slider shows uniform mechanical polishing wear, typical cosmetic transmission oil staining, and minor superficial storage oxidation from sitting in an inventory bin (as clearly detailed in the product photos), but it is fully intact and ready to clean, lube, and drop into your shifting stack.
