This LS Accessory Bracket Locator allows you to quickly compare all of the accessory brackets we offer for LS engines on one page. Each page is organized by accessory (first page is alternators) and shows the mounting position of the accessory relative to the water pump centerline, shown by the dotted horizontal line. The accessory starts in the highest mounting position on the passenger side of the engine. This begins at the top of the left of each page, then the accessory moves lower on the engine as you go down each column. When you reach the bottom of the column, then move to column 2, then scan from top to bottom before proceeding to the 3rd column, then move the the next page after this.

Inside the crankshaft circle, the dash numbers indicate which balancer spacings that specific part number is available in. Use these numbers to confirm proper spacing for your setup. At the bottom of each page, the color legend shows which accessory models fit this bracket. There may be multiple. For exact measurements of each part number, then go to the listing for that part number and look at the images to see the dimension drawing.
