These are the drive plates we use in our Camburg 2.25 rear race hubs. These are CNC machined in-house from 4340 chromoly, then heat-treated, stress relieved and electroless nickel plated for corrosion resistance. They are available in 5 on 5.5" and 6 on 5.5" bolt patterns for either 35 or 40 spline full float axle shafts. Unlike some, we precision broach our axle splines for a tight fit.
