ATI Pulley - Supercharger - 8.59 - 8 Grv - 2014+ LT1 LT4 Dry Sump 5 Percent OD

This 8.59-inch diameter pulley from ATI is made from solid aluminum, chosen for its light weight and ability to dissipate heat. It features 8 grooves to securely hold the belt and is designed with a 5 percent overdrive. This means the pulley spins the supercharger 5 percent faster than a stock, 1:1 ratio pulley, which can help increase boost pressure and improve overall engine performance on compatible vehicles.

ATI is known for making well-built components, and this supercharger pulley is no exception. The precise machining ensures it fits right onto your LT1 or LT4 engine's dry sump system, which is common in many performance applications from 2014 onwards. The 5 percent overdrive is a popular choice for those looking for a noticeable but not extreme increase in boost, offering a good balance between performance gains and maintaining reliability.

When installing this pulley, remember that it's designed to work with the specific belt configuration for your engine. Ensure you have the correct belt length to accommodate the 5 percent overdrive. This part is a solid option if you're looking to get a little more out of your supercharged LT1 or LT4 engine.
