Description

Complete Loaded Primary Drivetrain Assembly — Lifestyle Powersports Inventory Vault
Up for sale is a genuine, Harley-Davidson Factory OEM Big Twin 5-Speed Loaded Clutch Hub Assembly Kit (Built around master factory core number: #37550-90A / Cross-references Milwaukee Twins #68-502 [1]). Sourced from a clean warehouse layout, this entire used bundle comes completely loaded with the vital internal drivetrain components you need to drop straight into your primary case.
Unlike empty bare hubs that require buying separate plate packs and costly small hardware pieces, this complete setup is ready for mockup or final install sequence.
Product Specifications & Mechanical Parameters:
  • Brand: Harley-Davidson (Original Equipment Manufacturer - OEM Performance Core)
  • Component Type: Transmission Clutch Hub Core with Full Friction Plate Stack & Hardware [1]
  • OEM Factory Hub Part Number: #37550-90A (replaces legacy index #37550-90) [1]
  • Inner Hub Core Style: Modern 5-speed straight splined center bore (slides directly onto splined transmission mainshafts).
  • Platform Fitment Bounds: Direct factory drop-in replacement for standard 5-speed diaphragm clutch setups on 1990 to 1997 Harley-Davidson Big Twin Evolution models:
    • 1990–1997 Softail (Fat Boy FLSTF / Heritage FLSTC / Custom FXSTC / Springer) [1]
    • 1990–1997 Touring (Road King FLHR / Electra Glide FLHT / Ultra Classic FLHTCU) [1]
    • 1991–1997 Dyna Glide (Super Glide FXD / Low Rider FXDL / Wide Glide FXDWG) [1]
    • 1990–1994 FXR Series (Super Glide FXR / Low Rider FXRS / Sport Glide) [1]
  • Exclusions: Will NOT fit early 1980–1989 5-speed setups (which utilize a tapered inner hub architecture) or 1998-later models which carry a different backing plate tracking depth.
  • Included Components in this Listing:
    • One (1) OEM 5-Speed Splined Clutch Hub Assembly [1]
    • Complete matched stack of used internal Friction Clutches & Steel Drive Plates
    • Factory internal Snap Rings / Circlips
    • One (1) OEM Hex Head Mainshaft Clutch Hub Locking Nut
    • Matching outer Clutch Pressure Plates
  • Condition Details: Solid used builder stock. The reinforced steel center hub studs and outer aluminum alignment splines display straight, clean tracking parameters with minimal notched wear. The internal mainshaft spline tracking grooves are sharp, clean, and completely untwisted. Clutch plates, snap rings, and pressure plates show typical light, uniform wear consistent with normal operation. Staged in a light protective layer of storage oil to shield against warehouse humidity.
