The NonStopTuning Hyundai Genesis Coupe 3.8 Pulley Kit is designed for tuners looking to reduce weight and increase the throttle response of their engines.
These OEM diameter pulleys will neither underdrive nor overdrive the associated accessories, yet lead to great throttle response, and improved horsepower and torque numbers.
Each kit is CNC machined from 6061-T6 aircraft quality aluminum, and tested for tight machining and balance tolerances. Every NST pulley is hard anodized for exceptional durability and is available in a choice of colors.
The NST kit is compatible the OEM belt, we recommend a new belt (available bellow) for our high mileage customers.
