Found the thread, it was about finding the axle ratio. Now I just need to decide 4.6 or 4.9. Want to get 33/10.5/15 sure seems like they would work.

Found the thread, it was about finding the axle ratio. Now I just need to decide 4.6 or 4.9. Want to get 33/10.5/15 sure seems like they would work. 4.90s. ALWAYS 4.90s! If you're going to anything larger than a 32" dropping gears will be nothing but an improvement. A BIG improvement. I've had 4.63:1 with 29"s, 31"s, and 33"s. Little black had the stock 265s when I bought it. Eeah. Ok, but boring. It has 31"s now. Much less boring! Nothing to write home about power-wise - it gets over the 11,000+ passes in 4th ok-ish. I ran the big '97 on 33"s for a couple years with the stock gearing. THAT sucked. It worked and it was drivable but I won't do it again. Hard on the clutch. It certainly was not race car. It REALLY sucked off road. Effectively, its like having a 1.2:1 t-case ratio on the stock tires. Flipping horrible. To put you back to the stock effective ratio at the pavement, you need something like a 5.20. Not gonna happen. 5.13 or 5.29 are the available ratios. 5.38 - what I run - would be too deep for 33"s. Academic, since the 5-series was never sold in NA so you can't get them anyways. 4.90s will get you close. At your altitude it shouldn't feel a lot different than it does now if you had 31"s on it. Doesn't sound like much going from 4.63 to 4.9, but it is. I dropped from 5.38 to 4.9 year before last as a test and the difference was HUGE. I put it back almost immediately. Edward

Then I guess going to 4.9 from 4.2 on 31 should add some pep for now

Then I guess going to 4.9 from 4.2 on 31 should add some pep for now Uh, yes and no. If you want get-up-and-go, you need a bigger engine. Changing gear ratios changes torque multiplication. HP and torque are not the same thing. Ideally, you want a gear ratio that gets you into the power band and keeps you there the longest. So, for instance, if the power band is, say, 3000-4500, you want to get into that quickly, but you DON'T want the gears so deep that you blow straight through to 5000-6000. Assuming you don't change the engine, all you have is changing the gearing. In that case you have to settle for torque multiplication through changing gears and you have to carefully match that to the tire size and the engine torque and HP output. 'Fortunately', there are so few choices its really hard to do this wrong. Which is why I said '4.90s, ALWAYS 4.90s'. No way to go wrong with that ratio if you're running anything over a 32". The side affect of this, however, is that while you will get a LITTLE more 'pep', until you change tires you'll blow through 1st and 2nd a lot faster from at stop. The V5MT1 is NOT a race transmission. There is no such thing as 'speed shifting' that transmission. You'll be shifting through the first two gears a lot faster than you would with the 4.2 or even the 4.6. On the plus side, it'll be a LOT easier to get the vehicle moving from a stop. Deeper gears don't make a race car, they make a tractor. The stock tire diameter is about 30". With a 33" tire you'd need to go to the 4.6 to get back to the OEM ratio at the pavement. So, mathematically, you'd be exactly at stock with 33" tires. You then need to figure in rolling resistance of a bigger, less efficient, M/T tire - which is considerable, the extra weight, loss of aerodynamics and the extra weight of any accessories, add-on equipment like rock skids, heavier skid plates, bumper, etc. and extra stuff like recovery gear. Given all that, 4.90s - the next step deeper - are the logical choice. So, while - mathematically - these are deeper, the feel of the vehicle should be very close to stock if not just a LITTLE snappyier off the line. 4x4 Extreme Sports - Calculate Gear Ratio Tire Crawl RatioSomething else, too. If you add a bunch of weight and bigger tires - so load on the engine - the ECM will be more prone to go into Open-Loop Mode. That isn't going to do anything nice to your gas mileage. Ideally, you want to make your modifications in such a way as to keep the readings the ECM gets within the programed acceptable ranges set in the ECM. The 4.90s should do that nicely. Edward

My door jamb shows it was shipped with 225/75/15 w 4.2 gear. After I got it a bud was going to 33,s and gave me his cooper 265/75/15,s. Looks more like a truck now but its on 15x6 rims. So I'm looking to push the wheel out another inch with 3.75 backspace @ 7.5 inch wide. The tach is saying 3k @ 70 mph. But corrected its more like 78-79. Which is close to most o. nline calculated #'s (tacomaworld) Now by going to a 10.5/33 I don't really get much wider than the 265s but pick up another inch in height +/- So going outboard an inch or so really should not tax the components too bad. And should keep me from hitting the sway bar or the steering arms hsg.. So my gearing will keep up with traffic @ 4.9 w 33's. And hopefully no major rubbing issues. This is like when I put 225/50/18s on my scion xb only rubs lock to lock on steep driveways :cool:

I might be thinking about altering my own axle ratio as I'm in 33s now and feel like I'm going to get run over in traffic... would be nice to know how to find said 4.9 axle ratio... LOL! I was looking and found this... msport97.proboards.com/thread/11006/tell-gear-ratioMine is a 2001 xls. Came with Auto trans and 16 inch rims. Its had factory fender flares that were color keyed to the bumpers and had integrated side steps. based on that thread... would I have 4.6 ratio or was that only the older versions? What units come with the 4.9?

My door jamb shows it was shipped with 225/75/15 w 4.2 gear. And you have a 3.0L M/T. Same one my x fiancee has. With the 6" rims. That's the size the 'Wide' version came with, with the 7" rims. Both my '97s. Don't remember anymore what the 7" backspacing was. 8" is the usual next step wider. Be careful with tire and rim selection. Lots of stuff will 'fit' and work fine right up until you try to stuff a tire. I never had issues with 33x12.5x15" M/Ts on the stock rims, but CoSport with the same configuration but different brand tires had clearance problems at the lower back of the wheel wells when he got the tires at about 45 degrees and they started to stuff. Yes, again watch your backspacing. If you push the rims out - and yes, mechanically you shouldn't have any issues - you need to make sure when the tire moves up it won't hit the fender or the skirt inside. Edward

Its had factory fender flares that were color keyed to the bumpers and had integrated side steps. based on that thread... would I have 4.6 ratio or was that only the older versions? The gear ratio is on a tag attached to the rear axle. IF the tag is still there. Or if it was there at all. I don't remember ever having one on my big Sport and I got that new with 67 miles on it. What it came with from the factory is on the VIN tag in the engine bay. There are recent pic posts of VIN tags and you can see the ratio on the tag. That, however, assumes that the ratio was never changed AFTER it made it to the dealership. If you look at the pic in the thread you refered to, look where it says "Trans Axle". You'll see to the right it says "4272". That's 4.272:1 - so, 4.27s. The only 100% absolutely bullet proof way to tell is to pull the 3rd member and look for the stamp on the ring gear. Which sucks, 'cause if its never been pulled its a PITA. You can also do the turn the drive shaft and count the wheel rotations thing. I haven't done that since about 1985 - GM, Chrysler and Ford have too many ratios, too close together for that to be real accurate. My Pontiac has a 3.2something, a 3.3something, a 3.4something and a 3.5something. You'll never figure that out watching the wheels go 'round. For sure some of the Limiteds did. Apparently not all because my '99 3.5L Limited has 4.6. My '03 3.5L Limited AWD had the big 4.9. To the best of my knowledge, none of the Gen 1 2.4L came with the 4.9s. Nor any of the 3.0L LS models. Other than the high end Limiteds, I'm not really sure of the Gen 2 Sports. I remember talking to the techs many years ago about deeper gears than the 4.6 for the Gen 1s and was told that 4.9 was a dealer installed option. I looked the other day and 4.6 is the lowest showed in the FSMs. Edward

Saw the wheels I want at mitsu today... Same one's but 16 w 265/70/16 only .5 taller than my current shoes. But limited to 265 or 285 which are wider than my planned shoes.

I almost went with those wheels...those look like the Vision wheels Warriors. I went with the Vision wheels Raptors because they had sale on them and I preferred the Matte black look. Vision Warrior
