what do you think??

 

No =]

 

those are for 35's 410 is good for 33's that is if you have a 4.0L

 

he has a 4.0 4wd and that's a lotta dinero just to get a bit of speed back and hurt your gas mileage and whatnot.

 

I had 4.10 on my 285's and I still did 90 very easily... Not needed.

 

You'oll porbably get better gas mileage with the 285s and 4.10s

 

yeah the 4.56's is a little extreme

 

i bout laughed.........

NO......you will get somewhere around 10mpg because of the engine screaming......not to mention you probably wont be able to keep traction....

 

dont do it

 

dont you use 4.56's for 33 1250's ??? is that just for the weight of the extra width....

 

285 are essentially a 33 for a 16" rim. 33's and 4.10's are ample. My 33's on my 3.0 w/ a few mods was ample.

 

stay with 4.10's they have plenty of power.

 

I run 4.56's with 33's but the TSL's are a rugged tire and don't roll very nicely not to mention the rims I have are very heavy. The 4.56's give me the acceleration I wanted and great power off road. I barely have to floor it any more. At least I have needed to floor it yet I am sure they are going to get me into more difficult situations in the future.

 

I have noticed that in 4lo, my torque is insane. I have climbed my truck up massive snowbanks with only a tiny bit of throttle. I always wondered if it was 4.10 gearing, the engine, or 4lo that had the most pronounced effect.

Note in the pic below that my truck is on 35s, so the headlights arent near the ground.

 

in 4low my trucks power is more than I ever imagined it would be. I will show the power I had I know that with my 3.73's he was not get out of this hole by my truck.






His truck wouldn't start and that mud had him suctioned in there. I had to pull him out without any help.

 

Don't listen to them man, go ahead and do it, I mean you will never have to worry about another speeding ticket again. lol

 

yah and you wont want a speeding ticket, since you paid $600 to regear your truck.

 

I say do it. Look at a stock truck they come with anything from a 235x75 to a 31" tall tire and come with 4:10's and now you are running a 33" tall tire which puts you out of your powerband. A 4:27 or a 4:56 gear will put you back to within factory specs and since they do not make a 4:27 gear for our front axle then that makes the 4:56 the only choice to bring it back to stock.

with all that said you can run a 33" tall tire with 4:10's with no problems but you will not have the stock performance. Also as some people have stated you may get a little better gas mileage but that also really depends on how much your new 33's weigh because if they are heavy then your gas mileage will go down trust me.

 

Yeah but with a 4.56 he will have no top end speed.... Or at 65 he will be at 4000 or 5000 rpms

 

There's a lot of variables that no one knows or has even bothered to ask which would effect the optimal gear ratio.

1) Is this a daily driver?
2) How much freeway driving is there?
3) What is the top speed you travel?

Some people over at http://www.offroadrangers.com/forum have 32s & 4.56 gears, so you may want to checkout what they have to say about it.

That seems a bit exaggerated. I'm about 2.5K @ 65 MPH. I doubt a .26 change in gear ratio would double his RPMs...

 

Doc in over drive he would be right around 3000 rpm's at 65 mph with a 1:1 gear ratio in the trans so with a over drive trans he would be even less. here is the chart that i used.

 

i blew out my rear end w/ 31's so i had 4.56 put it... its sucks on the free way, but i did it so in the future i can put bigger tires on. i would recommend 4.10's. at 70mph i'm at 3k rpm. but thats not the problem. when my speedometer reads 70, i'm doing around 60. so my stock governer is 95, in reality, around 80. (which causes trouble driving on the Florida Turnpike daily)

 

i had 4.56s with 32s and i got about 12mpg if i was lucky. and the power was awsome. um i topped out at about 85mph. was it worth it? hell yea

 

tim how'd u blow out ur rearend with 31's?
