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 sea level | 4.1" · 18 PSI | 4.5" · 15 PSI

• Six sizes, from 3.8" (most boost) to 5.5" (least)
• Order with or without the matching belt — the belt length changes with the pulley
• 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.
