I recently purchased a 1996 SVT Cobra Convertible. I am trying too determine what gears it has. It revs to High RPM very quickly in first and second gear. Would the ratio more likely be 4:10's or 373's. I have not driven a cobra prior to buying this one. It has a Steeda shifter.

Thanks for your help.

put it up on stands
chalk front tires well
put in N

mark the tire at the bottom and the drive shaft

have a friend turn the tire 1 round
see how many times around the drive shaf turns

a hair more than 4.... 4.10

almost 4... 3.90

3 and 3/4 3.73...ect ect.

Put the rear up on stands and mark the driveshaft and one wheel. Turn the wheel one complete rev by hand and count the number of turns the d/s makes. If it's over 4, you've likely got 4.10s. if just under 4, probably 3.73s.

2X But be sure both tires turn the same. if not it will give you a false reading if it's a open diff. But being a cobra it should have a limited slip diff.

P.S. First gear in the transmission is really lowed geared just to let you know !st is 3.37 second is 1.99 and 3rd is 1.33 in my 98 transmission.

Check the casting numbers on the Differential...Call the dealer maybe have the tech guys do the work
