ATI Pulley - Supercharger - 9.00 - 8 Grv - 2014+ LT1 LT4 Dry Sump 10 Percent OD

If you're looking to get more boost from your 2014 and newer LT1 or LT4 engine with a dry sump system, this 9.00-inch supercharger pulley from ATI is a solid option. It's designed to increase the speed of your supercharger, which in turn raises boost pressure and can lead to improved performance. This pulley is a 10 percent overdrive unit, meaning it spins the supercharger 10% faster than a stock-sized pulley.

This pulley is well-built from durable aluminum and features an 8-rib groove design, ensuring a strong grip on the belt to prevent slippage, even under high loads. The 9.00-inch diameter is a popular choice for those seeking a noticeable increase in boost without pushing the supercharger or belt system too hard. It's a direct fit for the specified LT1 and LT4 dry sump applications, making installation straightforward for someone familiar with engine work.

When installing this pulley, ensure you have the correct tools to remove the old pulley and properly seat the new one. It's always a good idea to inspect your supercharger belt and tensioner while you're in there, as increased boost can put more stress on these components.
