Choosing the BEST Rear Gear for Your S197 GT500/ GT

[@brianrahuba6919]

373, my opinion is the best gearing ⚙️ . Drag car 410 . 373 for all around performance

[@JavierRamirez-kh1mo]

Hey I’m subscribed, can you please do 2013 ram with a 6 speed trans compare 3.92 vs 4.10 vs 4.56 cuz I’m not sure what to get !!! Thank you 🙏🔥

[@Twobarpsi]

Good info! Tire size let's you fine tune it. I'd like to see you try a 26". Smaller tire also frees up more rwhp, due to less inertia.

[@AllThingsBoost]

I hadn't ever considered it until I tossed in into the calculator on this video, I would also like to see the effects of a 26, effectively making it like I have 4.10s in the car.

[@Twobarpsi]

@@AllThingsBoost probably could hit 10.50s at 138 🏁🏁🏁!!

[@robertswift6101]

i had 4.10`s on my 07gt,,,switched to 3.73 for better highway driving,,,today i no longer take it on the highway and going to 4.56 gears

[@sierra5713]

Did you end up putting the 4.56 on? If so how'd you like them

[@robertswift6101]

@@sierra5713 nope not yet,,i hope by spring

[@masonland4295]

Man I just installed 3.55” rear gears in my 2012 coyote 5.0. The transmission is giving me issues it won’t shift right. It’s a 6r80 6 speed automatic. Help!

[@AllThingsBoost]

You will need to talk to your tuner. The revolutions per mile, measured by the wheel speed sensors and output shaft speed sensor affect how the car knows when to shift, and needs to be adjusted to match the new rear gear ratio.

[@mach183]

373 are the perfect gear for a gt500

[@jeffortman6395]

Where does it say on the rear axle your gear ratio? I have a 2014 mustang gt premium

[@AllThingsBoost]

It doesn't. There is a way to do it via counting driveshaft rotations per wheel rotations, but you'll have to google that. Or you could try a VIN search if it hasn't been modified to see what comes up for options

[@skylersmall6322]

Was 3.73 much of a difference than stock 3.31? Previous owner installed aluminum flywheel and dual dusk clutch on my 2009 so not stalling out this heavy car from a stop is difficult. I just bought 3.73s getting them put in next Friday but im second guessing it since 4.10 would be nice for druving without boost. This car is currently a daily driver not a drag car though.

[@AllThingsBoost]

The 3.73s are a pretty big difference, I think you'll like them!

[@williepennington6377]

thanks man im thinking for my car about getting a 3.90 or 4.10 for mine im around 550 wheel i think, i havent had it on the dyno, got the basic bolt ons, cai pulley, exhaust tune. do u think 4.10 is too extreme? i mostly just do street driving but im on a 305/45/18 et street R

[@AllThingsBoost]

Depends, for the drag strip, 4:10s will serve you well, hell I could probably benefit from going 4:10s to help get it out of the hole, but plug them into the calculator at your cruising speed and see if that's where you want to be at.

[@hithereperson8137]

Daily driver/street racer with massive cams, 4.56 work? (2006 3v GT)

[@AllThingsBoost]

Daily driver? You probably want better mpg then revving to the moon at 3000k rpm going 75mph. I'd say highest I'd go personally is 4.10s. But try out the calculator and see what works for you at cruising speed.

[@hithereperson8137]

@@AllThingsBoost my car only drives properly at 3000+ rpm with the cams I have

[@hithereperson8137]

@@AllThingsBoost you right though holy shit

[@ChrisThaDonStreams]

What gears would you recommend for a 2016 GT? 1/8 mile dig racing mainly

[@AllThingsBoost]

Probably 3.73s, but you know your setup better than I do. Calculate your gear ratio like I did and see what makes sense. If you are an auto I'm not sure, I don't have any experience there with gear ratios.

[@ChrisThaDonStreams]

@@AllThingsBoost okay thanks I’ll calculate thank you

[@Almighty_F30]

For rolls 3.73 would be better right

[@AllThingsBoost]

Gears have less of an effect once your moving unless you are going for a speed run where they limit you. Just choose an appropriate speed and trans gear to start in that puts you in your powerband.

[@Twobarpsi]

Heard ice tanks are only good for like 2/10s when you're in the 10s. Don't forget 7.5 gallons of water weighs 63lbs!

[@AllThingsBoost]

Guess we'll find out soon enough. I know what's not good for 10s, and that's getting timing pulled out with hot air 😃

[@Twobarpsi]

@@AllThingsBoost don't look for water in the desert...don't look for 10s in 90 degree heat 😃! Can't wait for the Fall! You need to go back on a 50F day!!

[@08Mamba24]

My 06 is in the 500hp range and it has 3:31 gears. What gears would you choose?

[@AllThingsBoost]

Depends on the goal. Street car and cruiser? I'd stick with the 3.31s. Race car? 4.10s. Want to feel a little more pep but not lose all fuel economy? 3.73s. There is not a one size fits all, but the 3.73 in my opinion is the most versatile.

[@08Mamba24]

Well I guess roll racing and drag.

[@AllThingsBoost]

@@08Mamba24 determine your speeds you want to end up at and in what gear, plug them into the calculator and see what is best for you. See what rpm you'll be cruising at. Future goals, ect, play around with it and see what you like best.

[@Twobarpsi]

I'd say 373.

[@08Mamba24]

Did you say that you run 20in tires on the back? If so how in the hell you get them to fit. Mine hade 275/60r15 and the rubbed against the shocks
