I recently just got a 96 mystic cobra, and the guy who had it before me put 4.10 gears in it. As of now the car has only a few mods (2chamber flowmaster w/ Hpipe, 9mm sparkplug wires, pro 5.0 shifter)... I am contemplating between the 4.10's and 3.73's.. cause as of now my low end if very sweet, but the high end kinda annoys me how it doesnt pick up that good w/ the 4.10's in it. Im basically just looking for the best of both worlds and i dont plan on really racing the car alot, just want a good street car. If anyone can post some info on what they think is better between the 4.10's and 3.73's id really appreciate it..

thanks again.

What do you mean by "doesn't pick up that good"?

Well it picks up and goes, but its just not what i expected, what im trying to say is that is it cause of the 4.10's? and ive raced a buddy of mine w/ a gt starting off at 65mph and we tied all the way. Dunno i just figured cobras should be able to stomp a gt no prob, at nomatter what speed. Thats why im asking about the gears cause i want the best of both worlds at the top end and low...

3.73s will make you slower. :)

A stock or near stock Cobra will be 'quicker' and 'faster' with 4.10s than the same car with 3.73s in straight line acceleration.

Now....the 4.10 gears will have a higher top-end even over the stock 3.27 gears but it'll take longer to reach that top speed because you'll be pulling it in 5th gear (overdrive) vs. pulling it in 4th with the 3.27s.

You may want to consider moving up to 4.30s if you are going to change gears.

What year GT were you running against? What gear ratio does the GT have? What RPM were you shifting at? What gear did you start in when ya'll went at it at 65mph? What gear did he start in?

Yeah! What tcrews said! :thumbsup:

If you are going to swap gears in your Cobra, I would go w/ 4.30's - not 3.73's!


I bought 4.30's for my '01. I should have them installed w/in the month.. :D
