Default What Gears are You Running?

I can't live with the stock 2.73s so I'm going to upgrade to 3.55s. Anyone running this ratio?

You will get many different opinions on this one. I have 3.55s in my '88 red SCHP 5-spd and really like them. They put the car in a range of performance and driveability ( haul but not over rev at sustained highway speeds) . If the car is an auto, you might want to consider 3.73s.

A lot depends on what you want it to do with it. IE: daily driver or howl the hides every time you leave the house (4.56s). Good luck with your decision.

I've ran both gears in my street Mustangs over the years and 3.73's are in my opinion, the way to go. You'll see around 2450 rpms @ 75mph on the highway with a 5 speed and 275-45-15 tires. If you have your heart set on going with 3.55's I have two new sets of Ford Motorsport gears for an 8.8that I will ship to you for $140. Please PM me if I can help you out...

Default 3.73 speedometer gear

I have a 3.73 in the WI SSP and the speedometer was way off when I drove it. I checked the gear at the end of the speedometer cable and it was a 21 tooth but some of the teeth were worn off which could count for the needle wondering. What did you guys do to get the speedometer close to accurate? I read that the trans drive gear in the 93s had 8 teeth and on the chart, it indicated I would need the max of 23 tooth gear on speedometer and it would still be a bit off. They also mentioned the nylon gears last a little while and then it may break some teeth like the one I have. The other choice was to change the trans drive gear to a 6 or 7 but it is a big job. Any help would be appreciated or will I have to just live with it. Thanks

Gary, I HATE 2.73's.....in anything so I don't blame you. I have 3.27's (original gear ratio) in the 93 FHP with the auto trans and it runs alot better than the 2.73's. I also plan on putting 3.55's in the gray coupe to make it more fun to drive.

I have this exact rear in my 85 (the original 7.5" rear is long gone). I like the 3.27's OK, but I am considering a gear change over the winter to 3.90's or 4.10's (keep in mind I have tall 255 BFG's out back). With the 3.90's and tall tires, my final effective gear ratio would be close to 3.73's, should I ever fix my speedo.
