Yeah, I have 3.73's and 31's and it is far from optimal. Someday gears lockers and tires in that order...
I dont think thats true at all every x i seen has had 3.73s and or think it was 3.55.ive never seen one with 3.27 omg!!that thing would be so slow and have no power at all!!
I have 3.27s on stock 235/75s and mine runs just fine. I mean, it is not like it has serious grunt, but I never lose speed going up hills, and I can pull fairly reasonably with it. I used it to tow my Lincoln home after the engine blew, 26 miles up and down hill and it never had any trouble. Accelerates just fine when I am getting on the highway, and it does what I need offroad. Plus, mine is an auto 4wd, so it is not like I have a drive train that efficiently delivers power..... It drives around just like I expect from a light truck though.
The one my ex took had 3.73s, as does my dad's, and they do have a bit more grunt, but honestly, a 3.27 is fine in a stock application. Think about it this way; GM likes to use even shorter gears than that. You could get blazers with 3.08s and 2.73s.
You talking full size blaze or small blazer?one way about 1000lbs less than an ex and one has a v8 i still think gears was my best mod so far.yes in stock form 3.27 would be ok for the highway
I meant S10 Blazers, and the 4 door ones weigh in at 3700 lbs, so they are only a couple hundred pounds shy of what an Explorer weighs, with roughly the same aerodynamics. But don't get me wrong, gears are the best mod you can do for an Explorer when you upsize tires and want to play hard off-road. Most bang for your buck, and doesn't take as much skill/time as a V8 swap. Plus, they work great alongside ANY mod you can do to your truck, including an engine swap. No matter what you do to increase power or performance, better gearing for what you want to do will make that mod better.
My current X does as well, but it's a lighter 2WD sport 5 speed. The 4 door autos I had were dogs. Once I put on 31's it was really bad on the HW. Couldn't get any speed to merge or pass. If I did it again I'd swap in a 3.73 or higher axle.I have 3.27s on stock 235/75s and mine runs just fine

My 94' 4 door 4x4 limited with 3.73 and 33 inch tires is the fastest one of my explorers. Most of them have the 3.73 gears and every single one except the limited has stock size tires.
It may have something to do with the 70mm mass air flow sensor housing, the large cone filter, or the flowmaster 40 that is dumped 12" past the muffler. A lot people will say those mods don't change much, but it seems to be more than enough to overcome the increase in tire size. When I first got this X it was stock and almost the exact same speed as two of my other explorers.
I have the 70mm housing with the stock electronics. How would I go about tuning it?That 70mm maf is just hurting your performance unless it was tuned for your truck

Thats the catch 22.two ways,the maf can be tuned or the ecm can be programmed for the larger maf.but in a first gen you prob wont find any one to tune the ecm and witch leaves you only tuning the maf.i think there is only like two or three maf you can tune and none are from a stock vehicle. If you dont have any major engine mods then the O2 should adjust for the larger maf but it will still run on the leaner side and especially during WOT.

That was the weight advertised bone dry without a driver. Under similar circumstances, an Explorer is just over 3900 lbs.Mine weighted in at 4601 with me in itbut yep totally agree.the OP said he was getting a 4" lift so im assumeing he will go with bigger tires and plan on 4x4ing it so i would say save for gears and dont waste any money on motor mods.
the post down the middle makes up for the marginally larger diameter. Overall, they both flow the same amount of air.
