It’s a loaded question because there are a lot of factors that go into deciding what your final drive ratio should be, including your engine’s camshaft and your transmission choice. Let Lucas from GearFX explain what you need to consider when you are trying to select a gear ratio for your vehicle.

Thnx for the breakdown, I'm exploring my 2011 Supercharged Jaguar XF. Was breaking down the specs as I get to know it and my first gear showed 4.17 , 2.34 , 1.52 on a chart. So I came here for a better understanding. She's aggressive 470 hp with 424 lb torque. This is gonna be fun!

Hello ! Thanks for all the info you talk about on your channel. I want to regear my TRD 2016 Tacoma, but I don't have any local place I can trust to conduct a professional job. My friend advised me I could buy a front and rear diffs complete with the ratios I want. I would remove and install the diffs in my Taco. Then I would send back my diffs for a core credit? Any direction would greatly appreciated, thank you.

I have a T5 transmission a manual 97 Camaro 3800 series 2 I’m thinking to change the rear gear differential any advice?😊

[@larryjoy2446]

How does tire size affect the end result of axle ratio, or does it affect it at all

[@Blad3.]

I have a sentra 1.6 5 speed manual, Rpm is too high on 5th gear, Is therr anyway to fit a lower ratio gear

[@rickyricon2787]

I just bought a 2005 silverado 1500 2wd 5.3 from the first owner , the paper work shows it has the 3.73. as a package option, a heavy duty suspension, GVW rating is 6,800 lbs. the truck is lifted 6 inches. does this means that the truck is more for towing than for crusing ? I just want to understand what I have Im new on this gear ratio thing...LOL

[@mmb1487]

Great video thank you

[@luisvelazquez1968]

What gears ratio would yall recommend. I have a extended cab 98 obs 1500, with n/a 5.3 sloppy stage 2 cam with 4l80e transmission combo? I believe currently it has 3.73 rear end gears.

[@alexandercharles2842]

what about 1.3 Litre MPV weight 1.2ton, 5 speed manual with 98hp and 109 Nw torque?

[@juanray2614]

Was sup bro, I have an 2007 crown Victoria P71 4.6L V8. I think I have 3.27’s but I wanna get more power of my car or at least make it faster at the tires. The weight of the car is heavy but she can go at lower RPMS but at higher RPMS I have to hit the gas the. She revs. Idk if I should go with 3.73’s or 4.10’s. Here a lot of the lose top end power on 4:10’s? I kinda want the best of both worlds what would you suggest? I have exhaust upgrade with K&N stock & a little tune on it. Maybe 4:10’s for faster speeds or 3.73’s for best of both worlds.

[@havencole1536]

What gear ratio would you recommend for a 2006 Cadillac sts-v

[@vunkeatfung2438]

May anyone give me a suggestion for VVT-I 1nr-ve engine with 4AT fwd car should upgrade to what ratio for better acceleration?

[@tycole8144]

I have a 68 Camaro making about 500 horsepower NA I plan on putting on a pro charger soon my 0 to 40 is very nice however the car begins to slow down after that like it’s running out. I bought the car with posi and I’m assuming 4.11 what would be gear for a 700r4 Camaro with 18 inch wheels. 600 horsepower

[@christophercruz6131]

What the best gear for my 68 chevelle with a inline 6 250 with a th350 transmission and I have a 3.08 with posi

[@exquisiteremodeling1]

What would you recommend for a 6.0l V8 gas engine with an automatic 4 speed overdrive transmission. The truck came with 245x75x16 but I’m running 35x12.5x17. It’s an 04 Silverado 2500HD

[@gearfxdriveline7047]

If you plan to do a lot of towing, then a 4.56 would probably be your best bet. If not, then 4.11 should suit you just fine.

[@Celticman197]

3.73's ,4.11's are only good for 1/8 mile. After a quarter mile there is no way they will keep up with a 3.25. You will see nothing but tail lights, and won't see anything afer a 1/2 mile.

[@hudsondonnell444]

Drag racing is overrated.

[@charlesparr3296]

Your overrated ​@@hudsondonnell444

[@Unpluggedcables]

​@hudsondonnell444 Nah dawg, drag racing is sick. It's the most basic form of racing but it's so hype just seeing those beautiful machines take off from standstill down the strip, and there is no other motorsport with better wheelies!

[@aaronbryan5095]

Only applicable if your crapbox is a relic that only has 3 to 4 forward gears

[@chrissellers5296]

It's a 1987 Chevy r10 pickup

[@chrissellers5296]

[@TheSwedshReaperr]

[@exquisiteremodeling1]

It’s 4:11 now, but it lags off the gate

[@gearfxdriveline7047]

Then a 4.56 might be your best option.
