Imagine hitting the trails in your Polaris RZR 800 or Ranger 800, only to feel sluggish acceleration and jerky engagement pulling you back from the adventure. Vibrations rattle through the cabin, belts wear out prematurely, and those steep hill climbs demand more effort than they should—frustrating when all you want is reliable performance on every ride.
Picture this instead: Smooth, responsive power that snaps to peak RPM instantly, quieter trails without excess vibration, and belts that last longer through mud, salt, and heat. Your outings become effortless, with crisper throttle control and confident climbs, letting you focus on the thrill of the journey rather than mechanical worries.
Our Primary Drive Clutch with 1.16" Bore Assembly from Bostome bridges that gap for your Ranger 800 (2012-2017) or RZR 800 (2010-2014). Machined to OEM taper, it installs directly without spacers or re-balancing to save you time. Dynamic-balanced alloy sheaves reduce vibration and heat for extended belt life and a peaceful ride. Pre-tuned weights and spring optimize 800cc power for quicker response and stronger performance. The anti-corrosion coating and high-pressure casting ensure it withstands tough conditions season after season.
Restore your ride's potential—add this Primary Drive to your cart today and experience the difference on your next trail.
