## Description

ACDelco Gold (Professional) Accessory Drive Belt Pulleys are a high quality alternative to Original Equipment (OE) parts. When the accessory pulleys are rotated due to drive belt motion, they cause the accessory drive belt to activate. ACDelco Gold (Professional) parts are manufactured to meet your expectations for fit, form, and function, making them a smart choice for General Motors vehicles, as well as most makes and models, including special applications. These high-quality parts are backed by General Motors. Some ACDelco Gold parts may have formerly appeared as ACDelco Professional.

Review: perfect fit and function - You have to use the old spacers that are locked onto the pulley with a push on nut. I drove the bolt out of the nut far enough to get a hold on it to turn it off, Then drove it on to the bolt after replacing the pulley. You may want to have an extra 7/6 push on nut in case you destroy the old one getting it off.
Review: Good product - It’s a pulley what can you say it goes around

It’s a pulley what can you say it goes around

### ⭐⭐⭐⭐⭐ 2001 LS1 Trans Am
*by W***B on November 26, 2019*

Replaced the pulley instead of the whole tensioner assembly on my 01 T/A. This pulley fits right, runs quiet, and works good so far.....FYI- I found the outer shoulders are not quite as thick as my original, which makes this pulley slightly narrower. Not an issue since it does not affect alignment.
