ATI Pulley - Supercharger - 9.68 - 11 Grv Serp - 2019 ZR1 LT5 - 20 Percent OD

ATI is well-known for making robust performance components, and this supercharger pulley is a prime example of their work. This specific pulley is designed to increase the speed of your supercharger by 20 percent over stock, which means more boost and more power for your 2019 Corvette ZR1 with the LT5 engine. It’s a direct replacement for your factory pulley, making the installation straightforward for anyone looking to get more out of their supercharged V8.

Crafted from durable aluminum, this pulley is built to withstand the increased rotational forces and heat generated by a supercharged engine. The 9.68-inch diameter is precisely machined to ensure it runs true and balances well, minimizing vibrations at high RPMs. By spinning the supercharger faster, you're forcing more air into the engine, which is a fundamental way to increase horsepower and torque. This pulley is a popular choice for ZR1 owners aiming for a noticeable performance gain without extensive modifications.

When installing this pulley, it’s important to ensure your supercharger belt is properly tensioned. A 20% overdrive pulley is a significant change, and it works best when paired with other supporting modifications that can take advantage of the increased airflow, such as an upgraded fuel system or engine tuning. This part is designed to fit your 2019 ZR1 LT5, offering a solid way to enhance your vehicle's performance.
