302T Pro Package (Pro R Turbo)
Eliminate Sheave Failure. Upgrade with RZRBlade.
If you ride a Polaris RZR Pro R, Turbo R, Turbo S, or Pro XP, your factory primary clutch is a known weak point. The cast inner sheave is prone to cracking under pressure, leading to blown belts, misalignment, and breakdowns. KWI’s RZRBlade upgrade replaces the stock sheave with a billet solution engineered to survive real off-road abuse—backed by our race-proven Groovix cooling system.
Engineered for Real Riders
From desert racers to weekend warriors, RZR riders push their machines harder than ever. The problem? Factory primary clutch sheaves in Pro R, Turbo R, Turbo S, and Pro XP models weren’t built to keep up. Our billet RZRBlade sheaves eliminate flex and failure at the source, so you can ride harder without blowing your setup.
Built Cooler. Built Stronger.
We didn’t just strengthen the sheave, we improved how it performs under heat. KWI’s Groovix Cooling Technology increases airflow behind the sheave, managing belt temperatures and extending belt life. This keeps your clutch consistent on long pulls, technical climbs, or high-speed dune runs. It’s not just stronger, it’s smarter.
Quick Swap, Big Upgrade
Send us your OEM inner sheave and we’ll replace it with a brand-new RZRBlade. No need to ship the full clutch or wait for a rebuild. We’ll install Groovix cooling technology, inspect fitment, and return your upgraded sheave ready to bolt in. It’s a simple, no-hassle path to stronger performance and long-term reliability for your Polaris Pro R, Turbo R, Turbo S, or Pro XP.

Why the RZRBlade Mod Matters
The RZR platform has evolved—power numbers are up, tires are bigger, and riders are pushing harder. But the factory clutch sheaves haven’t kept pace. Across the RZR Pro R, Turbo R, Turbo S, and Pro XP, the OEM cast inner sheave is a common failure point. Heat cycles, torque spikes, and aggressive riding cause cracking and distortion. That flex leads to misalignment, inconsistent engagement, and premature belt wear—or worse.
KWI’s answer is simple: Replace the problem, not the whole clutch.
Our RZRBlade billet inner sheave is CNC-machined from aerospace-grade aluminum to withstand the abuse factory parts can’t handle. But durability is just the start. The integrated Groovix Cooling Technology cuts belt temps by increasing airflow at the point of contact, giving you longer belt life and smoother performance under load.
Unlike other clutch mods, the RZRBlade upgrade is handled entirely in-house by the team at KWI. From precision machining to clutch inspection and reassembly, every step is done with expert hands and real-world testing. We don’t just build clutch parts, we run them hard, fix what breaks, and refine until they’re ready to win.
Whether you’re fighting heat soak in Glamis, hammering through rocks in Moab, or chasing podiums in the desert, RZRBlade gives your primary the strength and cooling it needs to keep up.
This isn’t just an upgrade. It’s the fix.
