This is our billet 40% (actual 43%) primary reduction for the DCT Rubicon and DCT Rancher 420. Model designation on frame decal must include an "A" such as TRX420FA. Requires clearance cutting in the front crankcase cover spacer in two small areas. Wide open auto shifting is affected but drive-ability is retained. If you choose to correct wide open auto shifting you will need one module for the Rancher 420 and two modules for the Rubicon.
