ATI Pulley - Supercharger - 9.40 - 8 Grv - 2014+ LT1 LT4 Dry Sump 15 Percent OD

This 9.40-inch diameter ATI supercharger pulley is made with an 8-groove design and offers a 15 percent overdrive for 2014 and newer LT1 and LT4 engines equipped with a dry sump system. The larger diameter means the supercharger spins faster relative to the engine's crankshaft, which directly translates to increased boost pressure. This is a common upgrade for enthusiasts looking to get more power out of their supercharged LT-based engine.

ATI is known for well-built performance components, and this pulley is no exception. The 8-groove design ensures a solid grip on the belt, reducing the chance of slippage, especially under high load. The 15 percent overdrive is a popular choice, offering a significant boost increase without pushing the supercharger beyond its optimal operating range for many setups. It's designed to fit right onto the factory or compatible aftermarket harmonic balancer for a straightforward installation.

When installing this pulley, ensure you have the correct tools to safely remove the old pulley and install the new one. Proper belt tension will be critical to achieving the full benefit of the overdrive and preventing premature belt wear.
