What is the main purpose of this crank pulley?

This pulley attaches to the crankshaft and is driven by the engine's rotation. It serves as the mounting point for your accessory belts, which in turn drive components like the alternator, water pump, and power steering pump.

What does the '10 Grv' mean?

The '10 Grv' indicates that the pulley has ten grooves around its circumference. This allows you to run multiple accessory belts, which is common on many LS series engines to drive various components.

What materials is this pulley made from?

This pulley is constructed using both aluminum and steel. The steel is typically used for the hub that mounts to the crankshaft, providing a strong connection, while the aluminum is used for the outer pulley section where the grooves are located, helping to reduce overall weight.

About this part

Product Details

If you're working on an LS series engine and need a new crank pulley, this ATI unit is a solid option. It's designed to bolt right up to your LS engine, giving you a reliable place to mount your accessory belts. The 2.62-inch diameter is a common size, and the 10-groove setup means you can run multiple belts for accessories like your alternator, power steering pump, and water pump.

This pulley is built with a combination of aluminum and steel, which helps keep the weight down while maintaining strength where it's needed. The steel hub ensures a strong connection to the crankshaft, and the aluminum outer ring is where the grooves are machined. It's a well-built part that should hold up well in daily driving or more spirited use.
