jk noob build

i have some 35x12.5x17s that i picked up, ordered up a teraflex 2.5in suspension lift and impatiently waiting for it to come in, currently looking for rims as i don't want to run the stock rims, and most likely going with a aev procal mod, my 08 jk unlimited rubi is pretty much stock (auto trans) is there anything else i need? wondering if id have to swap out my gears? think they running 4.10?, also should i run different flares or will i be safe with the suspension and rim set up?

Yes and that’s the only way they come, or, if you are asking about for the front and rear the answer is still yes. Also 5.13’s for the ’07 – ’11 with auto and 35’s is by far the most popular gears for that combo although some people go a bit lower (higher numerically) for various reasons.

4.10s run decent on 35s (3.8L) with a recalibrator tool. Look into the aev procal or the flashcal

If you have the Rubi, it's 4.10 gears. You have an even lower transmission ratio in low range, compared to the Sport and Sahara. A guy that works with me has the same Jeep as you with 35's and he says that the ratio is so strong that he can't even manage to spin his tires to clear the mud... So no need to regear for offroading, but it might be a little under-powered on the highways.

I don't think you have many highways in Nunavut, so your good to go!

Your lift is good for 35's, you don't need flat fenders for the tires to clear, but you can get wider fenders to cover the thread width. If you don't you can expect many rock chips. But many people don't bother with it unless the law requires them to.

You should get rims that are 8" wide and have sufficient back spacing. Four inches should be good.

The land in your area seems rocky, so I would look into skid plates and armour. The rock rails you have will save your tail a few times for sure!

yeah i guess i should be happy there is no highways here where im at (fly outa this hellhole to get out), fastest i could go on a road is probably 110km/h on a good day with nobody on that road and properly maintained as it's all gravel roads (but that is a very small stretch of road), other than that stretch of road rest are all pretty short, as for the rims i plan on getting some 17x9s, and the fender flairs im getting are just for the look, less is more on those to me yay smittybuilt, who cares about rock sctaches those are battle scars to tell about unless some *** key's your new jeep which they did to mine when it came off the ship

Sleeve and gusset the C's. good precautionary measure don't want to break an axle or c out in the middle of no where. I have an 11 with 35s well 315 at 28psi rolling height is more like 33.5" on a heavy 4 door with bumpers winch etc...I am still running 4.10 gears. Works fine for me I don't expect my jeep to be a rocket. It's a jeep. If I was in the mountains maybe I would change gears.

My daughter has a 2011, 3.5" lift, 35's and 4.10's. Seems to have as much power as it had with the stock rubi tires...

The OP might want to see how your JK performs before going with new gears.

Looks great! And very cold there.

I'll be the dissenting opinion on the 4.10's. When I was on stock 32's & 4.10's, it couldn't get out of it's own way. Acceleration was pitiful. Any kind of hill and it was downshifting to 3rd and eventually to 2nd (then it was screaming).

I have much better accleration once I swapped gears to 5.38's (appropriate for 37's). I believe the 5.13's will prove to be a happy combination with 35's.

5.13's on that Jeep is going to be your best bet. That is what I am moving to next month and they seem to be the most common gear swap for Jeeps. We can help you with that upgrade when you are ready!

JeremyatKOR, what's the typical cost to upgrade from 4.10 to 5.13's?

The gears and installation kit will cost you only about $500-600. Installation costs (labor) will run you about $800-1600 (depends on your local labor rates).
Expect to pay between $1200-2200 total.

If you are willing to drive to the Atlanta area, I know a Jeep mechanic who does gear swaps for $1500, everything included.

But believe me, it is money WELL SPENT!!!
