Description

This is a used, exceptionally clean V-Twin Manufacturing aftermarket replacement 5-speed transmission countershaft gear cluster assembly. Engineered as a direct mechanical drop-in for 5-speed Big Twin gearboxes spanning 1980 to 2006, this unit showcases V-Twin’s signature flat matte silver finish with zero surface polish or dark chemical coatings.
The geartrain cluster has been completely cleared of residual oil, bench scrubbed, and inspected under intense store workshop lighting. Every gear wheel tooth face—from the small 1st gear cog up to 5th—exhibits excellent structural integrity, fully free from under-cut shearing, deep contact pitting, or micro-cracks. The square shift-dog engagement windows are sharp and unrounded to prevent jumping out of gear under heavy acceleration load. The bearing journals are smooth and ungrooved, and the end retention threads are crisp and unstripped. It is an excellent, cost-effective replacement option for repairing a transmission case with a stripped or whining countershaft gear stack.
  • Condition: Used, excellent structural and mechanical health.
  • Specifications: Standard stock-ratio 1st through 5th gear arrangement; fits 5-speed Big Twin cases.
    Fitment
    Verified factory architecture matches 1980–2006 Harley-Davidson Big Twin 5-Speed Models (including Shovelhead, Evolution 80ci, and Twin Cam 88ci engines across Touring, Softail, and Dyna series platforms):
    • Touring (1980–2006): Electra Glide, Road King, Road Glide, Street Glide, Tour Glide
    • Softail (1984–2006): Fat Boy, Heritage Classic, Softail Standard, Night Train, Springer
    • Dyna (1991–2005): Low Rider, Super Glide, Wide Glide, Super Glide Custom
    Fitment Status & Engineering Details: Verified exact 5-speed component fitment corresponding to factory cross-reference OEM P/N 35632-79 (V-Twin catalog reference 17-0580). While mainshaft designs shifted multiple times from 1980 to 2006 to accommodate chain-drive, belt-drive, and splined clutch configurations, this underlying 5-speed countershaft geometry remained the core factory architecture for over two decades. It will not fit 2006-up Dyna or 2007-up Touring/Softail 6-speed gearboxes.
