What it does, is this: 3. Now, this means that your engine is spinning faster on 4. Which is great for towing and accelleration in the AV case or for Drag racing in other cases, This way the engine will reach it's max torque and horsepower RPM quicker and with less strain on the engine I won't even get into the taller tire relationship with the 4.

Your RPM's will be higher at cruising speeds. Can you say "Gas Guzzler"? I recommend opeing up the exhaust and making the intake modifications regardless of 3.

I have 3. But I do travel at about on the highway. Bottom line: 1. On the it puts the engine in the sweet spot most of the time and the gas usage is not that bad for the performance gain - if gas mileage is the desired goal I recommend the import hybrids.

It will allow you to tow heavier loads. If you put tires in excess of 33" on the beast you will need the 4. Charter Member. PM SM My first AV had 3. Between Both AV Ive only put miles. JonboyNY, do a search for 3. There has been A LOT of discussion about which ratio is better suited for this or that, so I'd suggest learning how the search works.

You'll find a plethora of good info on this widely discussed topic. Crocostimpy Charter Member. Basically I like to see at least revs while driving to have any kind of response, and the 4. Of course the rear-end on the is way beefier as well, which also helps in handling torque. Lightning Full Member.

If I had a vehicle with smaller engines like an SUV or minivan, then I would probably try to get the most efficient gearbox or transmission possible. The transmission and differential that work best with these gears would be lighter weight than originals installed on vehicles with 4.

For example, Chrysler V-6s are equipped with 3. I would also like it if I could install a slightly smaller size gear set for better fuel efficiency out of my engine bay, but it might be difficult to find a 4. Installing 4. However, it is better to have 4.

If you have two vehicles with an identical engine, one with 3. The same can be applied to someone who likes to race, especially those who like drag racing mph in less than 10 seconds. Anyone that likes drag racing knows how important it is to have a good reaction time after starting the car and while driving down the track. A vehicle with 4. The main reason that the 4. At extremely low speeds, only 2nd and 3rd gear are used and are therefore slower than the final ratio of 1st. On this particular website, the gear ratios are obtained by measuring how far a specific speed is placed in each gear.

In order to determine how far the vehicle travels in one complete rotation, engineering formulas must be applied to achieve an approximate velocity for one complete revolution. In this case, we will be taking into account how fast a vehicle travels at 30mph with 4.
