373 vs 410 Gears

[Ambitious_GinG]

Talked to my mechanic who i bought my marauder off of and asked him what he thought about the 410's and he told me 373's would be alot better to run. Any thoughts?

[jwibbity]

how about you read the hundreds of threads already covering this topic....:beer:

[Mr. Man]

Better topic would be 4.10's vs 4.30's in a non-DD car.

Find a new mechanic.

No, don't. He is correct.

im just curious i dont want to pay for the gear upgrade to then have to do it again in the future. I figured my mechanic new more than me so i just wanted to see the best option for the gear upgrade. Not close to a supercharger yet so i want to get my car to its bets without a superchrger!

Get the 4:10s , and a tune, and be done with it! , the best thing you can do for your car, there's only a thousand or so threads on 4:10s!

[Bluerauder]

3.73s are not even worth the effort. Go straight to the 4.10s and be done with it. 12 years of experience here says don't even bother with 3.73s.

Marauder comes with 3.55 gears , going with 3:73 wouldn't be that much difference
My 11 mustang I went from 3.15 to 3:73 and wished I did 4.11 or 4.30 gears

If I was driving your car, I'd go 4:10's.

But.... that's similar to saying... " if I was banging your girl, I'd..."
Why ask what anyone else would want? Do what you want to do.

Now, with that in mind , you may run into some driveshaft harmonic issues with the 4:10's.

IMHO 3.73 gears wouldn't be worth it as said before. Mine is a shared DD, between it and my truck. 4.10s aren't bad at all. Loose just a few MPG on the highway, gain a whole lot of acceleration. Running 75 MPH on stock size rear tires is right about 2500 RPM.

Get 4.10s, a tune from Marty and be done.
3.73s are for Mustangs. If you are worried about highway driving for a long time then stick with 3.55s. I've done 4.10s in two different marauders with no regrets. Only regret is not having a tune from Marty on the first one. :banana2:

Can you copy paste it here, says you have to be a member to see it

Is there a lot of traffic on that board?

What is 4.30's for $600 Alex.

Not a ton, more like a tight knit group of guys with others coming and going. I'll take screenshots in the morning.

I would install 4:10's. You said your not close to a supercharger YET, so it sounds like you are planning on installing one in the future. I had upgraded to 4:10's from the 3:55's a couple years before I put a supercharger on and I enjoyed those gears both before and now after the supercharger install.

Only thing I wished I had done at the time was upgraded to 31 spline axles and a better quality differential when the gears were swapped. It's ok though, you'll view the car different after the supercharger is installed. Good luck and HAVE FUN! :burnout::burnout:

[RF Overlord]

Going from 3.55s to 3.73s is only a 5% difference. 4.10s are a 15% difference.
Do you really want to spend that much money for only a 5% improvement?

Ask your mechanic for his exact reasons why he thinks 3.73 is better...we'd all like to know.

[jsignorelli]

I installed the 4.10's five years ago. It was one of the best things I did for the car. Now the stroked engine has a partner at the back of the car. The extra power gets transferred to the road. And yes... perhaps you need a new mechanic...sorry!

[djcrook73]

I bought mine with 4.30s already in it and thought they would be way too steep based on past experience with older cars with three speed auto and four speed manual trannies. I was quite surprised to see it tach just under three grand at 80 mph in fourth and the car can still bury the speedo for a short time if you're not scared of holding it at 5500 for a few.. if I had the choice I would probably use the 4.10s on anything that wasn't a long trip car. That is what my 2.73 Equipped crown Victoria is for. This car would be good for a 3.73 Swap so tell your mechanic I will just bring him mine ha ha.

thanks guys i appreciate the help i am going with the 410's for sure!

[VA-Mach1]

Another vote for 4:10's. I went from 3:55 to 4:10 in my 03 Mach 1 and it is great. You might want to look into a speedometer recalibration tool like this http://www.americanmuscle.com/ford-speedo-tool-9410.html?utm_content=Drivelin e+-+Other%7CFord+Racing&utm_campaign=05-14%20Years&utm_source=Google-pla&utm_medium=Shopping&utm_term=%7Bkeyword%7D&AMID=ford-speedo-tool-9410-GSBasicFitmentV1&year=2005&T5_Var3=blue&GID=50139 or a retune. If you use the recalibration tool make sure to run a positive from a switched sores and negative wire to the battery.

[Vortech347]

I've ran both 3.73's and 4.10's in Marauders. 3.73's didn't make a damn bit of difference. Do 4.10's or save your money for something else.

Your mechanic needs to stick to Mustangs cause he knows squat about 4000#+ cars.

355s to 373's may make a difference in a car light like a stang but would mean zip and a waste of hard earned $ in something as heavy as a MM - especially NA.

If some one starts giving you bs about mpg, ignore them. Difference of .75 mpg is not worth thinking about.

Get the 410s, you won't regret it! :burnout:

Good pick on the 4:10's. If I read correctly the ratio of this thread is 3:73 1 vote, 4:10 15 votes. Which proves your , mechanic blah blah blah. :violin:


4:10's are the :banana:

[DWSTANG67]

i dont drive all year but i would like to drive with 4:30 i have 4:10 and dove cross country but i think 4:30 would be more enjoyable.

I feel the same way! I have 4.10s, but I wish I would have gone 4.30s.

Would you put 4.10s or higher if it was a DD?

[justbob]

I had 4.30's and loved them. The only thing I found annoying was the highway RPMS at 70 and up.

I only switched to 4.10's to get the beefier pinion gear as I shattered damn near all the teeth off my 4.30's after the six speed install. Finally I had the gearing for stupid low RPMs at any speed well into the triples, but unfortunately not the effects of instant torque from a twin disc.

Stock 3.55's for the high speed win at 150+ mph.

Yall need to get out of the city traffic more often.

[crownvic05]

Get the 410s. When i had my 2000 crown vic lx hpp which come with 355 stock, i went to 373 and was a waist of time. 2 weeks later upgraded to 410s and then really felt the upgrade. It is always best to go 2 steps up when doing gears to really take full advange of the nice upgrade.

4.10's will easily do that. But when, where, why? Instant trip to jail... or worse.

[camelgrundle]

My 410's have done 140 plus with stock driveshaft and no vibration. Don't do it often but when a corvette is messing with ya it feels good to pass it lol.

[daddyusmaximus]

I am enjoying a small bit of a gearing boost due to my car coming on the smaller stock front tire 235/50/18 size tires on all 4 corners. If I was going to go to the trouble of a gear change, I'd do 4:10.
