Description

Upgrade your vintage Harley-Davidson transmission rebuild with this premium -0.020” Undersize Forged Steel Shifter Fork.
Engineered to exceed OEM specifications, this shift fork is essential for professional mechanics and builders blueprinting 4-speed Sportster and K-model gearboxes. Utilizing an undersize fork allows you to precisely dial in gear spacing, correct excessive side-play, and eliminate the gear-jumping common in vintage setups.

Premium Construction
  • Forged from High-Grade Steel: Offers superior structural integrity and resists bending under hard shifts compared to standard cast options.
  • Induction Hardened Pads: High-friction contact surfaces are localized-heat treated for exceptional wear resistance against the gear grooves.
  • Precision Machined: Ensures an exact fit to maintain critical factory clearances and smooth engagement.

Fitment & Specifications
  • Size: -0.020" Undersize
  • Material: Forged Steel
  • Replaces OEM Part Number: 34293-72A
  • Vehicle Compatibility: Fits all Harley-Davidson K-Models and 4-Speed Sportster models from 1952 to 1990 (including Ironhead and early 4-Speed Evolution models).
