285's and gearing

Who all has a V8 4x4 and changed gearing for 285's? And what did you go to and how did it affect gas mileage and driveability?
It already feels like a pig with 265/70/17's now.

Describe "feels like a pig"

I can tell I have bigger tires on mine (285's), but it doesn't really feel much different than it did with the stock size, well, not enough for me to think about re-gearing yet. I couldn't win many drag races with it now, but it's still not too shabby.
 
Probably like all the awd's feel. Feels heavy. But I'm thinking getting it back to the same ratio as with stock tires would be an improvement.
In my hotrod/drag racing days, I had a saying "gears will make anything run".

I have 285 Km2s (very heavy) on my Tacoma and love them. It's still fast enough for me, you just have to push on the pedal a little harder.

I'm not saying regearing wouldn't make a difference, just that I wouldn't regear for 33s unless you have a burning desire to spend a lot of money.
 
Change gearing for 285's on a V8??

First I've ever heard of that...

Hell, half the time people don't even change gearing on the V8's when going to 35's..

I would.

When I put on 265's I went to 4.10's. Brought me back to almost stock ratios with the larger tires.

If a 4.30 front would've been available I would've went that route for slightly lower gearing.
 
a burning desire to spend a lot of money.

You don't have to spend a lot of money. You can run any 8" rear third and getting a matching front from a 2005+ Tacoma. You can get 4.10, 4.30, and 4.56 from the factory.

With my 4.10 e locker rear and matching 8" front I probably have $7-800 all said and done. FYI, tacomas use a needle bearing in the front clamshell that needs to be swapped for a bushing. East coast gear can hook you up with the part, though.
 
I have 285 KM2 MT's on and to me there is no need to regear at all and I do not advise it.

4runner feels fine, yeah its little slower due to the weight but I am not trying to win any drag races with it.
 
I guess I'm the odd ball out here. I'm glad I regeared and I just went to 265's.

I hate an under powered and sluggish vehicle!
 
I ran 285s for close to 4 years without regearing. Although I don't have a V8, there was a slight difference at first but I quickly got used to it. I had thrown in 4:56 last year and have 35s sitting in my room waiting to go on shortly.

I have 285s on my V6 and I didn't even change the gearing. Really don't see the need to on a V8?
 
[MENTION=98608]Dpassmore[/MENTION] when I moved from 265-75r16 to 258-75r 16's I noticed a little difference under 2k rpms. Although it was very minor to me. When you get into the V8's torque band, it honestly feels about the same between 265's and 285's. Get near 3k rpms' and you will fill no difference.

That being said, it's just my opinion. It's the first V8 I've ever owned. You have obviously owned more, and may have more need for that low end instant power. All I can say is the power is there if you need it. It's just not there until you get into the torque band. Remember that the V8 has more torque, not horsepower.

Hope this helps, Greg
 
V8 4Runner sluggish? Man I guess I've spent too many years driving 4 banger tacos with oversized tires. Now that I've moved on to a V8 I feel like I'm in a race car. I mean according to motor trend a stock V8 runner in 2005 ran a 15.6 Quarter mile. That's fast by SUV standards. To do gears right it's pricey. unless you are already pulling the diffs apart for lockers I wouldn't I wouldn't re gear.

Define pricey...

I bought my e locker rear third with 4.10's for $400. I modified my housing and swapped it in. I picked up a matching 8" clamshell out of a 2011 Tacoma for $150. Swapped out a bushing and the long tube with my non disconnect and bolted the entire new housing in.

Doing gears and doing them right isn't that hard in toyotas. Especially when you have such a range in factory available ratios and most everything interchanges.

Actually you did good.

I used to swap gears in my street driven racecar monthly. The difference was huge. Stall speed and trans felt totally different.

Here's an experience I had once as well.

My grandfather gave me an old phone company van about 30 years ago. It had a 250 inline 6cyl. They were known for wearing the fuel pump lobe on the cam. It ran fine but at hiway speed it would run out of fuel at times. I wasn't worried about it because I was going to do a v8 swap eventually. The rear end was a 3.73. Before I did the swap, I came across a free rear end that was a 3.08. Since I knew I needed it for the v8 I decided to go ahead and swap it thinking it would drop the rpm on the 6 cylinder enough to help the problem of running out of fuel. It did drop the rpm, it did not however fix the problem, it made it worse. It took more fuel than with the 3.73. So much worse, I had to block it off and use a universal electric pump.
I would never have believed it if I didn't experience it.

So you are looking to increase gas milage? Or are you looking to improve "drivability"? I assume that meanswers you want more power? I'm just a bit confused as to what you want out of your regear.

I'm afraid you will never get your stock gas mileage back. To many other factors with the larger tires, and lift. Unless you over gear, and baby the piss out of your truck, and never drive highway speeds.

The gears would, however, give you more responsiveness, or "power", but it's going to be up to your personal experience to know if it's worth it.

Just for reference, front clamshells are virtually unobtainable in my area. My only options are ecgs, or a local shop.
