does my 08 gt500 gear is 3.73 going for 4.10
 
hey guys i just need an explanation on this subject. i think my gt500 has a 3.73 gear if i change it to a 4.10 gear how would this benefits me and the pro's and cons of having it.
thanks

If it is stock then your 08 gt500 has 3.31 gears unless again they were already switched.. So with that being silos what are your future goals ?
Do you plan to add s/c upgrade? If so I would not suggest 4.10 ... I would say 3.73 is the most u would want to go but even that I would say 3.55 would be better... I still have my 3.31 at my power levels and I couldn't even imagine going to 3.73... First and second are almost useless now with the torque and power... Hope this helps a bit

+1! I cant imagine having lower gears...at a 547 rwhp level in mine...I am well below TJ and I have to hit and shift 1st & 2nd pretty fast...

I had 3.31's and i'm getting 3.73's installed this week. I was at 650rwhp/612ft/lbs before the 10% lower, longtubes, o/r x, 72 lb injectors, and VMP BAP's. You have stock 3.31 gears unless yours is a KR (3.73's) :). I have heard 90% of positive feedback for people running 3.73's. 3.73's come on the '11/'12 GT500's with the SVTPP if I remember correctly. Most people state that going to 3.73's was the best mod they ever did. The 3.31's kind of fall on their face from a stop and also reverse is a bit of a pain. With 3.73's it is much more fluid from a stop and better street drivability. Many people say that 3.73's are what they should have came with and they are the best for street driveabilty. If you get serious about going to the track 4.10's. This is a popular topic that is talked about on the other forums. Get some drag radials and don't fear the gear!

I see i always thought that mine came with a 3.73, but anyways how would i know for sure what my gear is? Im the second owner of this car and im not sure if the previous owner have installed a different gear. How do i go about checking it.

adidasUNT8 04-22-2012 12:22 PM

Well your speedo would be off unless the person before you had it tuned and has it set to the new gear ratio. Have you had yours tuned, aka do you have a SCT tuner or something similar? I would go out driving around with a buddy of yours on the highway and agree to go a certain speed and make sure your speedometers match up. I'm going to go on the hunch that you have stock 3.31's.

BlackShelbyGt500 04-22-2012 03:45 PM

Oh i see i got this car from the dealer and it didn't come with a tuner so my guess is it is 3.31. So if i change to a 3.73 what whould i gain out of it? Quicker lunch from a stop? I really dont have any idea on how it works.

adidasUNT8 04-22-2012 10:06 PM

correct... your acceleration will be quicker. The trade-off will be you will lose some top end. But unless you plan on going to the texas mile that shouldn't be an issue...

BlackShelbyGt500 04-22-2012 11:16 PM

i see i think i'm getting this now so having a higher gear gives me more a chance against awd cars from dead stop? but not so much in the long run? do you think its a good idea for me to go with a 3.73 if i only drive the car on the weekend? i don't really go to the drag or the track just an occasionally run in to the freeways.

I will let you know in a few days when I get mine back from the shop. Everyone who has 3.73's say that the every day street driveability gets better. It's more fluid from a stop and reverse is easier to maneuver. In theory the 3.73 will give you better acceleration, but if you do not have traction, this is just going to blow the tires off more so then they already do.. I am running lower control arms and drag radials.

That is exactly what everyone told me when I had my Shelby.....3.73's were definitely on my "to-do" list...untill I got rid of her. I never came across one person who switched to a 3.73 gear and had anything bad to say about it.

haha, i like it.... also Drag Radials for the win.... i say they should come stock on these cars, only thing I dont like about nittos is you dont get much tread.

Actually having LOWER gears (those with a higher number, i.e. 3.31s are higher gears than the 3.73s) gives more power from the start but limits the top end.

I used to have a Willys Jeep pickup that had a Timken rear end with 5.38s ! That truck would climb a tree but literally would not go more than 55 MPH wide open and about to explode ! LOL
