2007 classic body style crew cab with the weee 4.8.

trucks a turd hoping that slapping gears init will bring it back to life. i plan to put an intake. some sort of muffler for now. and will work at headers and real exhasut and a tune.

but what gears? 4.10s? 4.30s? i will be puttin on a 32" ish tall tire. and then i haul bikes in the truck alot and it struggles

what should i buy? what should i pay for install??

 

If you dont plan on going bigger than a 32" tire then i would go with 4.10s. A 4.30 would kit your mpg. If your not hauling anymore than a few bikes then 4.10 would be great. What gears do you have in there now. Im dont know what the new ones come with. Maybe a 3.42?

 

mine has 3.23

i took a trip with 2 bikes gear bags coolers tools etcs maybe 800lbs of load. and the truck would down shift over every over pass. in cruise around 75. pretty aggervating for your truck to be screamin up a hill. so im hoping 4.10s will give it that extra oomph it needs for hauling and then roll on power around town. it seems like to pass or what not i gotta stomp on it to down shift for it to go anywhere

slowest truck ive ever owned. sad very sad.

 

Well you are going from a 3.23 to 4.10, there will a seat of the pants fell for sure. Go with the 4.10 and you will never look back.

 

If you are going to keep the 32" tires than 4.10s for sure.

 

yukon motive or oem

 

I vote motive, i have had good luck with these gears and they are priced just right.

 

OEMs are very good and install should be around ~$400 for rear only. I paid $1K front and rear including ring/pinion.

 

Motive or AAM 4.10s FTW.

Im not gonna say you wont look back. But when you press the gas youll forget about the drop in mileage.

 

i will say 410s atleast.. when i had my 30" tall tire at 70mph i was at 2200 rpms with 410s

with a 32" and 410s at that speed youll be around 1800 rpms

maybe 430s
