    Frequently AskedQuestions

    A gear reduction kit lowers your UTV's final drive ratio, increasing torque at low speeds for rock crawling, technical terrain, and sand dune climbing. It trades top speed for more pulling power and better low-end control.

    For Sand Hollow dune riding, gear reduction improves launching power in deep sand and reduces clutch stress. Combined with a clutch tune, it can significantly extend belt life and improve performance in loose terrain.

    We install gear reduction systems on Polaris RZR XP, Can-Am Maverick X3, Kawasaki KRX, and other major UTV platforms. We'll recommend the right kit for your specific model and use case.

    Most gear reduction installs take 2–4 hours. We'll let you know the exact timeline when you drop off.
