These are our American-made primary gear reduction offerings for the DCT Rubicon and DCT Rancher 420. Model designation on frame decal must include an "A" such as TRX420FA. The 25% will drop in without case mods. The 40% requires clearance cutting in the front crankcase cover spacer in two small areas. Wide open auto shifting is affected but driveability 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.
All of our reductions carry a lifetime warranty to the original purchaser. We've been making gear reductions for Honda's going on 10 years now with 20+ years of machining and metal-working experience. We've been repairing and modifying ATV's in general since the late 90's.
