This gear reduction consists of Polaris part #’s 3235380 and 3235381, also known as the 4 Seater Gear Reduction.  This is a stage 2 gear reduction consisting of the 27 tooth reverse gear shaft and the 46 tooth stage 2 gear.  This reverse shaft and stage 2 came in most 4 seat machines and can be used to reduce the gears in some 2 seat machines.  The total reduction is approximately 13% across high, low, and reverse.  We highly suggest you contact us before ordering gears unless you are absolutely sure what part numbers you are needing.  This is because of the variations in gear reductions from the factory and compatibility.  There is no warranty on Polaris gears and no returns.  This product is not eligible for any discounts.
