Description

Premium Transmission Needle Bearing (Closed Type) for Vintage Harley-Davidson Sportster & K-Models
Ensure smooth gear transitions and robust internal support with this premium closed-type transmission needle bearing. Precision-engineered to handle high radial loads and high RPMs, this needle roller bearing is a vital replacement part for restoring or maintaining classic Harley-Davidson 4-speed gearboxes.

Engineered for Classic Powertrains
  • High-Load Capacity: Drawn cup needle rollers maximize surface contact area, reducing friction and absorbing heavy transmission stress.
  • Closed-End Design: The closed-type (blind end) configuration seals off the end of the shaft to retain lubricating oil and keep external contaminants out.
  • Premium Hardened Steel: Manufactured from premium-grade bearing steel for exceptional durability and long-term wear resistance.

Fitment & Vehicle Compatibility
Engineered for perfect fitment in vintage Harley-Davidson 4-speed transmission assemblies:
  • 1954–1956 K-Models: Fits early vintage K, KH, KHK, and KR models.
  • 1957–1985 Ironhead Sportsters: Fits all 4-speed models (XL, XLH, XLCH, XLS).
  • 1986–1990 Evolution Sportsters: Fits early 4-speed Evo models before the 1991 transition to 5-speed gearboxes.
