Alternator

[Rummie]

Hello everyone, just curious on suggestions for a replacement alternator for my '06 Sierra, (5.3 crew cab, 4X4). Anyone put a higher performance part in there or just stick with the DELCO part? I have ripper out the air box and replaced with K&N Open Air, and there is a Magna Flow on the back end, but other than that not much is different...Thanks, on a side note there is a lot fo talk about whining steering when you turn left, I have that too any suggestions/thoughts?

How about 300 amps

Might have to look that brand up...DC POWER?

What does the OEM part for a 5.3 typically put out??

My '06 is rated for 145 amps. I think the other options for our truck was 105 or 160 amps, don't remember which right off hand.

A good alternator choice for GM pickups: http://www.hardworkingtrucks.com/high-output-gm-1500-alternator/

If you put an alternator that puts out more amps than the one that came off, do you need to do anything to the electrical system? Especially if you jump all the way up to the 300 amp range?

105 from 99-04, 145 05-14, 160 on 2500 and 3500's with plow prep package

According to the build sheet, my '14 has a 150.

I meant to put 13. But if you want to get technical, 2014 SUV's had 145 amp alternators

Well I'm talking about 1500 pickups, since that's what we're talking about. According to the GM parts sites for the 1500 with the 5.3 there is a 150 and a 170. Just letting you know and wasn't trying to get technical, I was just saying what mine is on my '14. If you meant to put 13 then that's all you had to say....

Anyone? I am good with car AUDIO electrical...but not sure about this question here...

You should do the big 3. Run 2 big ass grounds, and one big ass power from alternator to battery. I used 1/0 AWG from batt+ to alt. Then batt- to frame and frame to engine block
