ATI Pulley - Power Steering - 4 Grv - 15 Percent UD 5.5 Nissan RB26DETT R33/R34 Skyline

This is an ATI Power Steering Pulley specifically for the Nissan RB26DETT engine found in R33 and R34 Skylines. It's designed to be a 15 percent underdrive pulley, meaning it spins the power steering pump at a slightly slower speed than stock. This can help reduce drag on the engine, freeing up a little more horsepower.

The pulley features four grooves, which is important if your setup uses multiple accessory belts. The 5.5-inch diameter is a key specification to ensure it works correctly with your existing belt system. ATI is known for making well-built components, and this pulley is no exception. It's a solid option if you're looking to fine-tune your engine's accessory drive.
