Default GEARS

<P>From the factory mustangs usually come with a 2.73 gear ratio unless you have an svo which in '84 they come out with 3.45 and in '85 and '86 3.73 was standard.┬* Yoe had 2 options for different gearing in mustangs: 3.08 for 5-spd cars and 3.27 for autos.┬* Changing the gears is one of the first things that i would do to a stang.┬* Then we get into choices of different ratios.┬* so here is my opinion on this subject.┬*┬* First you have to decide what you want to do with your mustang.┬* Is it going to be a daily highway driver?┬* A Sunday Driver? Will you be stuck in the city(stop and go traffic)?┬*┬*or just a weekend dragracer?┬* You basically have 6 choices for gears:┬* 2.73, 3.08, 3.27, 3.55, 3.73, and 4.10.┬*┬*┬* the first 3 gear ratios are better for top-end, high speed performance, and the all important fuel economy to the highway commuters. 3.73 and 4.10┬*are better for┬*acceleration and┬*low end┬*responsiveness.┬* the gear ratio that i have left out was┬*3.55.┬* it is kind of an all around gear you get fuel economy and still have the power to pass cars at will on the free way.</P>

MORE THAN LIKELY YOU HAVE A7.5 REAR END AND I WOULD RECOMEND THAT YOU CHANGE IT OUT FOR AN 8.8 REAR. THE GEARS ARE PROUBALLY 2.73. I WOULD GO BACK WITH SOME 3.55 BECAUSE YOU WULL NOT HAVE ANY OVERDRIVE UNLESS THIS IS JUST GOING TO BE A RACE CAR.

Theres nothing wrong with that 7.5 rearend as long as you dont go running slicks on it!And being that it was a 2.3 and a 5 speed it most likely has anywhere from 3.08's to 3.55's.My 1989 2.3 with an A4LD had 3.73's from the factory.And i am still currently running the 7.5 and have been for 3 years now behind a 331 with no problems at all.</P>


Now thats not to say everyones is that good.If you can or you happen to run acrossan 8.8for cheap i would get it for sure and atleast keep it until the 7.5 gave out.But running around on the street on regular radials you shouldnt have a problem.</P>


To tell whats in your rear look at the rear axle tag or lift the car and count how many times the drive shaft turns in comparison to the rear wheels.</P><edited><editID>TheGmKiller331</editID><editDate>38023.9970833333</editDate></edited>
