What kind of Axle is this?

Hello Guys, I've been reading the forums for sometime and finally decided to register. I got a wrangler 2006 4 cyl couple months ago and it has been modified. I am trying to figure out what kind of axle it has, to me it seems its the ford 8.8 according to this
Ford 8.8 Cover - Differential Covers - Spyntec Industries LLC.
but I just want to make sure before i get excited. haha.

Definitely could be an 8.8, it is shaped wrong to be the OE Dana 35c.

Could very well be a 8.8...but who would put that in a damn 2.4 cyl Jeep? Unless PO planned a swap.

Because even a 2.4L or 2.5L can generate more than enough torque in 4Lo to snap a D35c axle shaft with larger tires and/or a locker.

Car came with 35" tires, so I assumed it has to be a Ford 8.8. I need to know because I'm thinking of switching the gears as it only runs up to 75 MPH.

For 35" tires, you want 4.88 gearing if you have a manual transmission. The 8.8 axle originally came with 3.73.

It is a manual tranny, 6 speed. So I need 4.88 gears front and back?

The 8.8 came with just as many different ratios as Jeep axles..

I think he was referring to the Jeep being called a "car."

Thing is, the "Jeep" loses power to 55 going uphill. Thats the only reason I'm looking into regearing.

On another note. The extra tire on the back is a 33" street performance tire for the city. Would it be wise/cheaper to just switch over to 33" street tires for the city so it matches the gears and switch tires when going off roading? From my observations the last owner probably did that, as the extra tire doesn't match the ones on the jeep.

Thanks.

Welcome to the wonderfull world of 4 bangers. You will never get it to do any better, no matter how you gear. Only thing that works is downshift. Or a 4.0

So you wouldn't recommend me to switch to smaller street tires?

Well, going from 35 to 33 isn't such a big difference so..If you moved to 31 you may notice it doing a bit better. But it all depends on the gears it has now.

Again, even with the stock 215 tires it will never make it up a hill in 5th gear.
