One of the most important steps of your swap is to identify the "spacing" needed. This "spacing" is determined by the crank pulley that you have, or will be getting.

Here at ICT Billet we design our brackets based off these three spacing principles.

• (-1) Corvette/CTS-V/SS(sedan)/G8's crank pulleys are in this category. See guide below for measurements
• (-2) 1998-2002 Camaro/GTO's crank pulleys are in this category. See guide below for measurements.
• (-3) All Truck/2010-2015 Camaro's crank pulleys are in this category. See guide below for measurements.

What this means to you?

All of our systems function around this spacing concept to ensure the kit is a direct bolt up to your application and proper functionality.

We categorize our parts by a 6 digit part # and a (-) at the end. Depending on which application the bracket was designed for would determine the last digit.

Example: Part# 551577-2 is a high mount alternator bracket for a LS1 Camaro. Same Part# 551577-3 is same bracket system but for a Truck engine with stock crank pulley.
