    My 4:10 gear o.k.?

    My 2007 Shelby GT is going super charged next week (550 Whipple)

    Is the 4:10 gear I have now O.K. with this mod?

    P.S. I don't race - strictly street fun.

    You should be good to go. I had 4.10's in my 05 GT and was great. Granted it wasn't supercharged. But first gear is going to wind up so fast. If your worried gas mileage that will definitely suffer.

    Haven't used first gear in three years -leave in second. Also not worried about fuel. Love the gear, but the unknown for me is the correct gear for supercharged.

    410's Are so much fun Just make sure you have some good tires and a good clutch when charged.

    If your running 20's i would go with the 410 gears. The 373 are good with 18's and a supercharger. 410 gears do launch hard. Get sum quality tires.

    Nittos probably wont be enough, I would suggest a BFG at least, or better yet the hoosier.
