gear ratio

Ok, so I followed some advice on this forum to determine rear end gear ratio. I jacked up rear end and marked with a paint marker the inside of wheel and also marked a spot on driveshaft. I am getting about 3 and 1/8 turns to every 1 wheel revolution. Stock, the car came with 2.73 gears. So any idea what gears I have?

What is your rpm to speed ratio... if you go onto AM's website and go to there gears, they have a speed chart that tells you your rpm's at different speeds for all the different gear ratios. Check your rpm when driving at around 70 and compare it to there charts. That might give you a general idea!

Op have you looked for or at the tag on the diff cover for the the ratio? Generally when they've been changed the tag gets removed.

I think the tag is still there. I'm going to go to AM website and look for their speed/rpm chart and double check. They could be stock 2.73's though.

Ok, just went driving and at 70mph with O/D off I was running about 2700 rpm. At 60 mph with O/D on I was turning 1700 rpm.

Re: gear ratio

They are 2:73 rear axle if it is stock and thats what was a friend of mins 98 and my 97 when we changed gears. The cobras are the ones that had the 3:27 This link even proves it

I never said there wasnt, I know that had 3:27's as a option. I over looked that he stated it was a automatic. With it being a automatic I would say 3:08 then because before i changed mine in my 2000 GT I was getting little bit higher RPM's and it had 3:27's . My 97 and a friend of mine's 98 was manuals and they have 2:73 in them.
