The fan comes complete with all necessary hardware for installation, including bolts, gaskets, and seals. The installation process is straightforward and can typically be completed in a few hours, making it an excellent choice for both professional shops and DIY enthusiasts.

In summary, the Maximum Motorsports BNU5XD Single Groove Billet Pulley Fan is an excellent investment for any GM Pontiac engine with 326, 389, 400, or 455 cubic inch displacements.
