if its a gs, it calls for the higher cca's 900 would be dandy.
when buying a battery if you live in a cold area, you always want the highest CCA'S you can get. in my last truck i had 2, 1,000 CCA battery's hooked up, helped a ton with snow plowing. with one single stock battery, when i worked the plow the volt gauge would get pinned to the low side bottom, dim the lights. installed the two 1000 cca's and the gauge would flick 1/2 way down, and then climb back up a bit. and the plow moved much faster.
