Unlock the full potential of your Polaris Ranger 150 by optimizing your gearing. Whether your young rider is tackling tough trails, hauling around the property, or pushing for maximum off-road performance, changing your rear sprocket size is one of the fastest ways to drastically alter how the machine performs. We now offer this high-performance upgrade in two distinct styles to fit your wrenching needs: a traditional Solid sprocket or our innovative Quick-Change Split sprocket, both precision-machined specifically for the Ranger 150's unique bolt pattern.
Choose Your Style
-
Solid Sprocket: Our classic, ultra-durable one-piece design. This is the perfect option for standard maintenance, full tear-downs, or builds where the rear axle will already be removed.
-
Split Sprocket (Quick-Change): Say goodbye to pulling the rear axle! Our innovative two-piece split design allows for lightning-fast, hassle-free sprocket swaps right on the vehicle. Whether you are making a quick trackside adjustment or tuning in the garage, you can change your gearing without removing your axle, wheel hubs, or carrier bearings. Simply unbolt the halves, swap your sprocket, and get back on the gas.
Dial In Your Gearing
-
Larger Rear Sprocket (40T - 46T): Increases low-end torque and acceleration. Perfect for tight trails, steep hill climbs, and navigating challenging terrain where quick response is critical. (Note: This will slightly reduce overall top speed).
-
Stock Gearing (39T): The balanced performance intended by the factory.
-
Smaller Rear Sprocket (37T - 38T): Increases top-end velocity. Ideal for long flat stretches or open fields where you want higher cruising speeds at lower RPMs. (Note: This will reduce off-the-line acceleration).
Made in the USA Performance
These are high-strength aluminum sprockets, proudly machined right here in the USA. Switching to our lightweight aluminum sprockets—whether you choose the solid or split design—significantly reduces rotating mass over heavier stock components. This provides snappier throttle response and improved overall drivetrain efficiency.

Gearing Pro Tip: The 1:3 Rule
When fine-tuning your Ranger 150, keep the "1:3 Rule" in mind: Changing 1 tooth on the front sprocket is equivalent to changing 3 teeth on the rear. Because the front sprocket is much smaller, a single-tooth change there has a much more dramatic impact on your gear ratio than a single-tooth change on the rear. Use your front sprocket for macro adjustments, and your rear sprocket for dialing in the perfect micro-adjustments.
