depends which trans you have and tire size...
2005 GMC RST *sold
2006 Silverado SS with nawz
35's run 4.56 for almost perfect gear ratio. 4.88's if you ever plan to go bigger. 33's or lower run 4.10s. i have 36's with 4.56's and at 70 im klicking 2300 rpms, when i had 33's and 4.10s i was at about 2400ish rpms.so id get 4.30's if you want some more bottom end with 33's or lower. this is all with a 4l60e
Today 03:25 am 6 stringer o thats a good point, its ok ill just add a blinker fluid cooler
Today 03:24 AMtruckinL33 that's not a good place for it, you can overheat your blinker fluid with the capacitor
Today 03:23 AMtruckinL33 i need them for when i go back to 1985
Today 03:23 AM6stringer i mounted my flux capacitor next to my blinker fluid resevoir
Today 03:22 AMtruckinL33 me too, right next to my flux compasator!
Today 03:22 AM6stringer hey gear oil needs to be cooled, i have front and rear diff coolers
3.90's best street gears. Otherwise you'll just burn the tires off. In my experience. But maybe I need better tires!
