What's a good gear size to go up to for 32"...maybe 33'' on D35 with 4.0l. I'll admit I don't wheel as much as I'd like to and it's my daily driver. That being said, I need it to get on the highway and still move while staying strong off-road when I do get there. And a locker is not out of the question though I'm not sure it's necessary since I don't plan on hitting any 6 or higher trails any year soon!

With 31's and 3.5" of lift already, I have felt the difference in not only power but vibes as well. It's not bad at all but should get worse with bigger tires and vibe at different speeds also, would it not. Besides, I'd rather upgrade now than fix later.

If you have the 4.0l and you plan on goin with 33's then Id go with 4.56. Im gearing down to 4.56 only Im droppin a D44al in the back first. Dont gear a 35 because your gonna want somethi bigger later on...TRUST ME :mrgreen: . Plus if you want to lock it up your going to have to buy 30 spline shafts especially on 33's. Otherwise you'll constantly be snapping them. If you arent goin to buy a locker and your just thinkin about stayin on 32's and you really want to regear than go to 4.11's. But once you gear and add lockers your talkin about a whole new ball game cause your gonna need to upgrade either the whole axle or at very least the shafts in a D35. A super 35 kit can be purchased for $1000 which has a detroit locker, 30 spline shafts and new bearings. Then you figure $400 if you can get off cheap for new gears and master install kits for the front and rear. Then if you want to lock the front D30 than your gonna want new shafts for that too. Its gonna be alot more $$ than you want to spend. If your keepin it as a DD and your like me and want locked axles as well Id save up your pennies to swap in a D44al that already has 30 splin shafts and just gear it and lock it. The only locker available is the Aussie which runs $250. So you can probably get off cheaper lockin and gearin a 44. Plus you'll have a stronger axle and its a driect fit swap. No weldin, cuttin, or grindin! Good luck on your decision, hope this helped.

thanks for all the info. I'm realisticly goin up to 32's with putting the spacers back ontop of the lift. I know this isn't the best setup but I'm not sure I want to go all the way with my only car. That's money down for the next one! If this becomes my project then I would definitely swap axles and get steel bumpers and winch and the list (as we all know) goes on.

One other dumb question, if you re-gear the back (whether it's a swap or current axle) do you need to go with the same in the front?

Of course.. That is, unless you'd like to see your transfer case explode when you put in 4WD.

that's what I thought. so even if you swap out the rear with a 44a, if the gears are different, can I still drive it to the shop in 2 wheel drive to have the front gears installed? or is that another recipe for disaster? I can probably swap out an axle with some help but I'm not trying to change the gears my self.

tear down is easy; re-assembly is out of my reach!

It take out the front driveshaft just to be safe. But yeah. You'd be able to drive it right down to the shop like that.
