Default 430s the Best Gear for my 04 Edge

Im wanting to do a gear change on it to pickup up some towing power and some grunt on the hills around here, its bone stock,auto trans with 373s in it right now,I was considering 410s not sure if that would make much difference.I know it sounds kind of extreme but years back i went from 327s to 411s in my mustang 5.0 with an auto and it was perfect,it picked up all around even gas mileage picked up on the freeway.Seems to me these automatic transmissions are power hogs and need all the help they can get...
Thanks ahead for any replies,,,jim

You still running stock tires?

I would go with the 4.10's my self unless your running 35" tires

Ive got stock tire size on my truck and it was standard with 4.10 gears. Its a huge difference between a 3.0 with 3.73 and my 3.0 with 4.10. City and mixed mileage sucks to the extreme but if the whole tank is on the highway then im getting about 22 to 23 mpg. The power is a lot better on take off and 4.10s can make the 3.0 move very well!

I imagine that 4.30 with stock tires would give you about the same mileage on the highway as me but city driving will leave you broke at the pump. Sure will take off though! I would say that if you have any tire smaller than a 35" then 4.10 gears would be the very best choice with both power and mpg.

I just did a breakdown on a Calculator online its with a 28 inch tire and the automatic in OD .75 @ 70 mph

373s 2349 rpm
410s 2583 rpm
430s 2709 rpm

surprisingly there is a big difference between 373s and the 410s 234rpms @70 between the 410s and 430s only 123 rpms

Also I was just reading there was an FX4 Ranger that came with 456s from the factory,first i heard of that...jim

Mine runs a tad higher due to needing to be retuned from the intakes and higher flowing shrtened exhaust. Getting to the speed slowly will make it an extreme challenge on keeping it below 2500 rmp. In my auto its very hard to work mpg by keeping it below that point in acceleration. I just aim for 3000 rpm most of the time.

The highest gear ratio from the factory is 4.10. No one has come up with proof the exist in North America

I would just try and find a rear end with stock 4.10s and swap it.

Intake and exhaust should have no effect on you RPMs. Gear ratios are the only thing that changes your RPMs.

^^^Right on. The only Rangers that came with 4.56's are diesel Rangers. Last time a diesel Ranger was for sale in the states were in the late 80's.

It will change the rmps if the fuel mapping is thrown off due to less restrictions in the intake and exhaust area. It is running lean due to the mods and when a engine runs lean it has to run more to achieve the power it would already have with a correct fuel mixture. When tuned and fuel mapped, the engine will give more power with less rpms due to correct mixtures of air and fuel.

I think your talking about power. I am talking about RPMs. It doesn't matter what you do to your truck if you don't change something in the drive line its not going to change your RPM's. You can tune, add an intake, change the exhaust even put in a new motor. If your truck did 60MPH at 2200RPM its going to stay that way unless you change the transmission gear ratios, tire size, or axle gear ratio the RPMs are going to be the same.

I am talking about power but power is directly proportional to rmp. If you are able to accelerate to 30 mph at 2500 rpm in 5 seconds with the correct fuel mixture then a lean mixture will cause you to have to take the rpm higher. So then top get to 30 mph in that same 5 seconds then it would take about 2800 rpm. The engine has to work harder to achieve what it should properly do. Get what im saying? I know that mods wont change rpm but as long as the mixture is lean then the engine will continue to work much faster to achieve the same power that a better mix does.

I understand what your saying and its partially right. But if you are in lets just say 2nd gear at 2500RPM and that gets you 30MPH. Then if you are in 2nd gear again and go to 2800RPM you are going to be faster than 30MPH. Just because your motor is working harder to get there doesn't mean that your RPM is going to go up. It will take you longer too get too 30MPH but your RPM is going to stay the same.

well you understand what im saying then. cruising rpm will not change but the acceleration rpms will increase to compensate for having less power. if your motor works harder then the rpm is higher. work equals the amount of rpm and power is put into the task. As rpms grow to redline at 5500 rpm then the engine is working much more than if an engine was approaching 3000 rpm.

In other words... I cannot wait until I can afford a SCT X3 and get dyno tuning time at my local dyno shop. That way my 3.0 can work less and put out more power.

I understand what you are saying but your not understanding what I am trying to tell you. Crusing RPMs, acceleration RPMs or any RPMs are not going to change unless you change something in your drive train. It doesn't matter if you have a 500HP or a 30HP motor in your Ranger UNLESS you change the transmission gear ratio, axle ratio or tire size the RPMs WILL NOT CHANGE. What will change is how fast you get to your desired speed.

I loaded a torque/trailer towing tune from Brenspeed, and can switch back to stock at any time. It takes about 90 sec to make the change.
It's just another option to consider.

I see you have cab light on the Ranger. Do you have any pictures of them up here. I want cab lights on my Ranger but am too much of a chicken to put them on.
