Product Details and Specifications

This power steering pump features a cast iron housing for durability and long service life. The inlet attachment uses a hose barb design, while the outlet is threaded with a 16x1.5 size, providing secure and leak-resistant connections. The pump includes a power steering reservoir but does not come with a pulley or mounting hardware, so these components must be sourced separately. The pulley attachment type is press-on, which is common for many GM power steering systems.
