Rolled Spline Barshafts

GKN barshafts are used extensively in WRC, Touring Car, GT and Rallying applications and are manufactured to the highest quality. Shafts are individually designed and manufactured to suit each customer’s requirements, from Formula Ford and Clubman Racing right through to WRC and beyond.

Key features:

  • extensive use of certified aerospace materials
  • incorporate hollow, shot peened shafts offering the ultimate in strength and weight
  • available in a range of finishes
  • the process of cold rolling helps reduce the stress induced during manufacture in the critical area of spline run out, therefore increasing strength and fatigue resistance.

GKN barshafts can be manufactured as a solid barshaft or a gun drilled hollow barshaft, with bore diameters ranging from 12.5mm to 20mm.
