Description
Boost your Audi 3.0T’s performance with the XLR8 179mm Overdrive Crank Pulley, engineered to deliver the perfect dual pulley setup for aggressive power gains. Designed to overdrive the factory Eaton TVS1320 supercharger, this lightweight pulley is ideal for those combining it with a smaller supercharger pulley and dual pulley tuning for significant horsepower and torque increases.
Crafted in the U.S.A. using T6061 aluminum and 316 stainless steel, this modular pulley system provides exceptional strength, zero-gram balance, and aerospace-grade precision (.001” tolerances). Unlike the stock Audi crank pulley, which is prone to failure due to its bonded rubber isolator, the XLR8 pulley features a more reliable bolted two-piece design, eliminating common factory weaknesses.
Perfect for Audi owners who want reliable, high-performance supercharger pulley upgrades, the 179mm crank pulley is a key component for dual pulley configurations that dramatically increase boost and improve throttle response through reduced rotational mass.
