Gboost Worlds Best Drive Belt Polaris RZR Pro R

Gboost Worlds Best Drive Belt Polaris RZR Pro R

Engineered to tame the massive power of the 2.0L ProStar Fury four-cylinder engine, the GBoost "World's Best" Drive Belt is the ultimate drive belt upgrade for high-horsepower Polaris RZR Pro R models. Built to withstand shock loads from 400+ HP machines, this belt surpasses even high-end EX and Sand Storm lines to deliver unmatched durability, thermal management, and power transfer.

Manufactured under strict ISO-14001, ISO-9001, and IATF-16949 quality certifications, this belt features 3rd-generation high-twist Kevlar cord construction and advanced BZX1 high-modulus rubber compounding. Precision-ground sidewalls ensure ultra-smooth clutch engagement while drastically reducing operating temperatures under extreme dune, trail, and race conditions.

Directly replaces and upgrades Polaris factory OEM part number #3211226.

Features:

• 3rd Gen Heavy-Duty Kevlar Cord: High-twist Kevlar tensile cord wraps over bottom cogs to deliver maximum tensile strength and extreme shock-load capacity.

• 400+ HP Shock Load Rating: Built to handle extreme torque spikes, high-horsepower dyno tunes, and aggressive launch setups without cord separation or snapping.

• BZX1 High Modulus Rubber Compound: Infused with short Kevlar fibers for superior heat dissipation, enhanced belt-to-sheave adhesion, and lower running temperatures.

• Enhanced Top & Bottom Cog Architecture: High-rigidity top cogs prevent sidewall bowing while allowing rotational flexibility; optimized bottom cog design increases shift efficiency.

• Precision-Scuffed Sidewalls: Precision-ground sidewall angles guarantee smooth engagement, reduced clutch slippage, and maximum power delivery to the tires.
