You are going to have a shop do the work right?

 

Changing gears needs to be done by a professional. Doing the work requires special tools.

 

Chances are, if you don't know what gears will work then you probably don't have the ability to change them yourself.

 

I would recommend asking your local mechanic what gears to get, or let them take care of everything.

 

If you still want to order the gears you need an 8.5" ring and pinion for the rear and an 8.25" for the front. Do you have a preference in brand?

Well.....Don't feel bad,I didn't notice the "back wheel" either,What gave it away for me was the 5th & 6th digit of the VIN..."C1" which denotes 2wd 1/2-ton.

I agree. It's one thing to buy the correct ring and pinion set in the ratio you want, but the installation must be done by someone with the experience and proper tools to do the work. An experienced mechanic will need about two hours to do the work with the truck raised up on a lift.

 

Yo didn't mention what country you live in, but finding a mechanic with experience in rear-wheel drive vehicles (not to mention experience in differential service) will be very important

 

Once you find the proper ring and pinion for your truck, Summit Racing would be a good place to order as they will ship to other countries.

Well I'll be even scarier then :lurk:

The VIN he provided is for an '07,Look at the 10th digit,Its a 7 which denotes an '07 model-year vehicle (It would a 6 for an '06)

Also I can tell you that its an '07 "Classic" GMT800 truck by the 12th digit being a 1,If it was a "new-body style" GMT900 truck the 12th digit would be a 5

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
