Polaris RZR PRO R Supercharger Pulleys

Boost is a pulley choice. Smaller pulley, more boost — and the right size depends on where you live and what you're running.

• 3.8": 21+ PSI at sea level, 17 PSI at 4,000 ft — belt Bando USA 6PK1285
• 4.1": 18 PSI at sea level, 14 PSI at 4,000 ft — belt Goodyear 1060514 (6PK1306)

• 4.9", 5.2" and 5.5": larger pulleys for lower-boost setups — ask us which one your tune calls for
• Order with or without the matching belt
• Every pulley change needs the matching tune

Elevation takes boost away; a pulley gives it back. Pick the size for the boost your fuel and tune support at your altitude, and order the belt with it — the belt length changes with the pulley.
