I wanted quad 250 amp alternators in my Chevy Silverado. All the quad alternator brackets I found we're cheaply made to expensive and didn't allow access to the power steering pump, so I decided to make my own.
I picked up a power steering pump bracket for my 5.3 liter from the junk yard since I had to make the brackets to fit the power steering pump bracket.
I then made templates of 1/4" hardboard to mount the 4 alternators to.

I then test fit the hardboard alternator brackets on my Chevy Silverado. I had to move the PCM forward twords the radiator and re-route 1 ground wire for lower alternator clearance. Amazingly I only had to trim 1/4" off the length of the brackets so it would clear the fuse box.
Then used the 1/4 hardboard templates and my wood working router, a 3/8" carbide flush cut bit to copy the templates in 1/4" 6055-T6 aluminum plate. Here's what the aluminum brackets look like after routing.
Here's a pic of what it looks like installed on the 5.3l motor. With 4 AD244 lage case 250 amp alternators, Gates 06~10 Ford f350 1251 (125 5/8") off the shelf heavy duty belt.
Here's a pic of the 4 alternators all wired up with runs of 1/0 welding cable and wiring harness. To a single battery which is really nothing more than a distribution block now, with a little stored reserve power.

With a little more than 1000 amps of potential power my truck radio amplifiers are much happier now and there are no more dimming lights while rockin out.
I plan on ditching the lead acid batteries adding a bank of 3 or 4 AGM batteries and a power inverter so I can run power tools off the truck and power the house in an emergency power outage (I'm still shopping for a 10k inverter - any recommendations?). I'm also looking at adding a 12,000 lb winch to the front. Still deciding on a snow plow and salt box. I don't think we get enough snow here in southern IL to justify the cost of a plow and salt box though.
All in all adding 3 extra alternators under the hood was a lot easier than I thought it would be and I'm very happy with the end results. Heck I can even check the power steering fluid level too, plus I saved a lot of money doing it all myself.
Questions / comments are welcome - Thanks
