Swapping a Cummins engine into a Ford truck is an increasingly popular upgrade among diesel enthusiasts, offering incredible power and reliability. However, one challenge many face during the swap process is adapting the accessories, especially the air conditioning (AC) compressor and alternator (Alt). Fortunately, the Ford AC bracket is designed to solve this problem efficiently, enabling you to keep your factory Ford AC compressor and alternator when upgrading to a 5.9 or 6.7 Cummins motor in your 1989-2018 Ford truck.n this article, we’ll dive deep into the benefits, compatibility, installation, and other crucial details you need to know about this innovative bracket, so you can make your engine swap smoother and more cost-effective.
What is the Ford AC/Alt Bracket?
The Ford AC/Alt bracket is a specially engineered adapter designed to fit your factory Ford 6.4 AC compressor and alternator onto a 5.9 or 6.7 Cummins engine. It is compatible with Ford trucks built between 1989 and 2018, making it a versatile option for a wide range of engine swaps.
This bracket eliminates the need for cutting, custom AC lines, or modifications, which are often necessary when using non-factory parts or mismatched accessories during engine conversions. By using this bracket, you can maintain the reliability and performance of the Ford-engineered AC compressor and alternator without complicated or costly adjustments.
Why Choose This Bracket for Your Cummins Swap?
- Keep Your Factory Ford AC Compressor and Alternator
Many truck owners prefer to keep OEM (original equipment manufacturer) parts due to their proven reliability and performance. This bracket allows you to retain your factory Ford AC compressor and alternator, which are designed specifically for your truck’s electrical system and cooling needs.
- No Cutting or Custom Lines Needed
One of the biggest headaches during engine swaps is modifying or fabricating custom AC lines or electrical wiring. The Ford AC/Alt bracket removes this hurdle entirely, allowing a straightforward bolt-on installation using your OEM compressor bolts. This saves time, money, and frustration.
- Compatibility with Cummins Tensioners
The bracket is designed to work with the 1994-2002 12/24v Cummins tensioner (Gates 38157), ensuring proper belt alignment and tension. This seamless compatibility further reduces installation issues and helps maintain the longevity of your serpentine belt system.
What’s Included in the Kit?
The bracket kit typically comes complete with everything you need for installation:
- AC/Alt bracket adapter
- All necessary hardware and gaskets
- New water inlet
- OEM AC/Alt compressor bolts (reuse your existing ones)
This all-in-one package streamlines the installation process, so you won’t have to track down extra parts or fabricate any components.
Recommended Serpentine Belts for Your Setup
Proper serpentine belt selection is vital for smooth operation and accessory longevity. Here are the recommended belts based on your engine type:
- For 12/24v Cummins engines: Use Gates K060840 serpentine belt
- For Common Rail (CR) Cummins engines: Use Dayco 5081325 or Continental 8PK3365 belt
Using the correct belt ensures the proper grip and tension, preventing premature wear or slippage during operation.
