Looks amazing!

Thirty minute install and part of that was getting the tools. Get or borrow a 24mm socket and a screwdriver or bolt can stop the pulley from spinning. Super happy with the improvement!

Dominick,

Thank you for your 5 Star Review of the Perrin Alternator Pulley! We are glad to hear that the installation process was quick and easy for you, with the only minor delay being the acquisition of the necessary tools. It is great to know that you are pleased with the improvement it has made!

Regards,
