A gear reduction lowers your ratio inside the transmission to put more torque to the ground.\u003c\/p\u003e\u003cp\u003eBecause the reduction happens inside the gearbox rather than at the hub, you get a clean, efficient power increase without adding lift or unsprung weight.

Because Polaris used several different reverse-shaft configurations, the correct kit is matched to your machine's OEM reverse shaft and tooth count rather than by model name alone. SuperATV offers multiple reverse-shaft OEM options (for example 3235224 \/ 29T, 3235380 \/ 27T, 3235451 \/ 25T, and 3236689 \/ 23T) covering dozens of Polaris part-number applications. Confirm your exact Polaris model, year, and OEM reverse-shaft number before ordering. Fitment is not guaranteed on applications not listed by the manufacturer.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eWhat does a transmission gear reduction kit do for my Polaris?\u003c\/h3\u003e\u003cp\u003eIt lowers your gear ratio inside the transmission to deliver more torque to the ground. That helps with bigger tires, slow-speed crawling, and heavy loads, improving acceleration and low-end power without sacrificing reliability.\u003c\/p\u003e\u003ch3\u003eWhich gear reduction percentage should I choose?\u003c\/h3\u003e\u003cp\u003eChoose 13% for mild gains on stock or slightly larger tires, 25% for bigger tires and mixed terrain, or 38% for maximum torque in mud, rocks, and deep technical riding. Bigger tires and heavier builds generally call for a larger reduction.\u003c\/p\u003e\u003ch3\u003eHow do I know which kit fits my Polaris?\u003c\/h3\u003e\u003cp\u003eFitment is matched to your machine's OEM reverse-shaft number and tooth count, not just the model name. Confirm your Polaris model, year, and reverse-shaft OEM number against the fitment list before ordering.\u003c\/p\u003e\u003ch3\u003eWill this make my Polaris slower on top speed?\u003c\/h3\u003e\u003cp\u003eYes. Reducing your gear ratio trades some top-end speed for more torque. Most riders find the trade worthwhile because the added low-end power dramatically improves real-world performance with larger tires or technical terrain.\u003c\/p\u003e\u003ch3\u003eHow hard is it to install a gear reduction kit?\u003c\/h3\u003e\u003cp\u003eInstallation requires opening your transmission, so basic mechanical experience and standard shop tools are recommended. SuperATV provides step-by-step instructions, and live guidance is available through their Virtual Mechanic service.\u003c\/p\u003e\u003ch3\u003eIs a gear reduction better than portals for more torque?\u003c\/h3\u003e\u003cp\u003ePortals add both lift and reduction at the hub, while this kit delivers reduction inside the gearbox for a direct, efficient power transfer. If you want more torque without changing ride height or adding unsprung weight, internal gear reduction is the cleaner solution.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eWhy SuperATV\u003c\/h2\u003e\u003cp\u003eSuperATV builds drivetrain parts under its Gear Driven Performance line, engineering gears for strength and smooth operation. This gear reduction kit uses 8620 chromoly steel with heat-treated, precision-ground teeth so it holds up to the added stress of bigger tires and aggressive riding.\u003c\/p\u003e\u003chr\u003e\u003ch2\u003eComplete Your Polaris Torque And Tire Upgrade\u003c\/h2\u003e\u003cp\u003eA gear reduction kit is the fix for lost torque after going big on tires. Before ordering, confirm your Polaris model, year, and OEM reverse-shaft number, then choose the 13%, 25%, or 38% reduction that matches your tire size and terrain. Pair it with a heavy-duty clutch kit, upgraded belt, and reinforced axles to keep the rest of your drivetrain strong under the added load.\u003c\/p\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"What does a transmission gear reduction kit do for my Polaris?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It lowers your gear ratio inside the transmission to deliver more torque to the ground.
