This is a 540 amp EXTERNALLY REGULATED alternator for GM applications. External regulator Is included, it comes with our single channel external regulator.  Need multiples? Message us at Facebook.com/brandxelectrical for a bundle price and a single regulator to control them 😊.

 DO NOT purchase this alternator if it’s something you plan on driving / daily driver - these are a competition ONLY alternator made for running lanes / burps etc - these are not made for demo vehicles. The chances of overheating an alternator with this much output is higher than any other unit - it’s not unreliable - we just like making sure people running alternators for demo vehicles have the appropriate output alternators for their application. Message us if you’re looking for the largest demo alternators we carry - we’d be happy to help! 

expect 240-250 amps at idle depending on idle rpm.

this is the largest automotive alternator on the market, any questions feel free to ask, we’re happy to help! 

Every unit comes with a lifetime warranty at parts cost, all units are built to order and generally take 2-3 weeks for shipping.

Solid shirt for the price — looks sharp and fits great
Color: Light Grey, Size: 3X-Large
I picked up this COOFANDY long sleeve shirt for work and casual wear, and overall I’m really happy with it. The fit is true to size and it’s not too tight or too loose — just a clean, regular fit that looks good on its own or tucked in. The material feels comfortable and not overly stiff, which is nice since I wear it all day. It has a crisp look but still feels soft enough to wear without feeling like you’re in a dress shirt all day. The stitching and buttons seem strong, and the shirt holds up well after washing without shrinking or losing shape. I also like that it’s easy to iron (or even just hang up right after drying) and it still looks presentable. The collar stays in place and the overall style is simple and classic, so it works for interviews, work, or even going out. For the price, this shirt is a great value. It looks more expensive than it is, and I’d definitely buy another color. If you’re looking for a reliable everyday dress shirt that fits well and looks clean, this is a solid option.

Nice shirts! Fit perfectly!
Color: Dark Green, Size: Large
REALLY nice shirts! Bought dark green and black for my 23 year old son before he left for his six month cruise job to East Asia and they look to not wrinkle at all, plus they fit perfectly and look great! He's 5' 10" and about 170 lbs and wears a large. It fits a little loose, but he likes it that way. I would highly recommend these shirts!

Color is off, but still a nice shirt.
Color: Brown, Size: X-Large, Color: Brown, Size: X-Large
The shirt is great as far as quality. Material is very nice. Hubby wears an XL, and I bought the XL and it fit him perfectly. He is 5'11" and weighs 210lbs. The reason I gave a 4 star, and not a 5 star is because I ordered the brown color. When you look at the brown option on the color option, you will see from my pictures posted that I did not receive a brown shirt. What I received was more like a rust color or a copper color. I kept it because I actually liked it. But Amazon needs to do better with their color descriptions. If you're looking for a genuine brown color, this is not the shirt for you.
