Well my alternator has gone bad and was thinking about up grading to a 200 amp alt. not sure if it would hurt my truck by running at size. What would you suggest i get as well or should I just get another stock one?

 

I'm running a 200 amp with no problem.

You can run as many amps as you want, as long as the alternator can keep from overheating.

 

I'm running a 200A as well. They do get damn hot...

 

just upgrade to a dr44g from a 03 ss. 145 amp alt all you need is a bigger belt. Ive seen these bench test around 160 amps at 2000rpm and 100 amps at idle.

Can be had new for around 100 bucks.

 

Whaaaaa? $100, **** my stock 105a i think ran me like $130 or something stupid like that ... Lmfao I might get one for my truck, do you have a link for it?

 

Are you talking about the 03 Silverado SS trucks? If so, my truck came with the 105 alt and not the bigger 145. The larger 145's came on the 05+ SS trucks with the electric fans. Regardless, I run a 200 amp alt now and its doing fine.

 

did you guys up grade to 4 gauge wire as the main charge wire when going with a 200 amp unit?

 

and you guys doing any thing extra to cool 200a off?

 

no need to do anything different for a 200a, and use 0 gauge, do the big 3....

 

I got a 250 amp because of audio , had it for 2 years and its works fine,no overheating or any other problems
