> [@texases](#): > > I bet I would notice very little difference with the ratio change. Higher rpm’s on the freeway, very slightly better acceleration. Not worth all the time and money to me. i don’t know some people on youtube and online say that it rlly brings the car to life and gives it more of a kick, i get its not a massive difference but it seems like a fairly sensible and a not too risky mod to do. So seems fine by me. time wise, its a mod that wouldn’t take much time, 5hour at mechanics and then a tune then done. Money wise i get it its a little pricey but its do able. ---

> [@Nevada\_545](#): > > I have changed gear ratios in at least 4 different vehicles and was not disappointed in the results. The smallest change was going from 3.21 to 3.55 in a truck, great improvement when entering the highway. yeh most people that i have seen that have done this mod online/youtube have been very satisfied by it so apart from the 1k price tag i see mostly positives. ---

> [@Mustangman](#): > > I swapped 4.10s for 3.08s into a 165 hp 1/2 ton Suburban.

You read my post backwards or maybe I wrote it backwards… I had 3.08s, I installed 4.10s for better acceleration. Maybe I’ll reword that. ---

> [@VOLVO-V70](#): > > Do you think the ones who spent the money for this and were disappointed are going to make a You Tube video ? Not likely. That’s a very valid point. it just seems hard to believe that some would be disappointed from this mod. I’ve seen this mod labelled ‘best mod/ best bang for buck’ for this specific car (mustang v6) on many platforms, forums and on youtube. I personally don’t think i would be disappointed: its a fairly simple mod that doesn’t require too much time which won’t put too much stress on my engine. Its literally one of the only performance mod that i could do which might make a difference and not blow my engine. ---

Seems like a reasonable inquiry, those who say that changing the gear ratio won’t make much difference could share their experiences. ---

I was thinking about supercharging this one as well, but before I commit the many thousands of dollars that would require, I want to see what the upcoming S650 has to offer just read your post on your trip to the dyno after installing your headers, very impressive! yeh i was thinking of getting headers too for a while, thought they’d be an interesting mod. ---

Swapping out the ring and pinion takes some specific tools. I went the other way, swapped in a taller one on my Duster when I broke the old one, it didn’t hurt the acceleration much, but this might not apply to your case. It was an easy swap of the entire axle. Not an option here. What transmission do you have? ---

It was an easy swap of the entire axle. Not an option here. yes i would take it to a shop, from what i’ve read i don’t have what it takes to do this mod myself and for 500 bucks its not worth the risk of me destroying my car. Did you swap the axle yourself? was that not too hard? ---

My local pick-a-part shows 6 2005-2010 Mustangs with complete rear axle assemblies, at least one is a GT. $175 for the rear axle assembly, I would search for the lowest gearing (highest ratio number) available. I had a 318 Duster with the standard 2.71 rear axle, I replaced the axle assembly with one having 3.21 ratio. 15.8 seconds in the quarter mile with a four barrel and headers, it makes a difference. A stock duster is about 17.5 seconds in the 1/4 mile. ---

> [@Nevada\_545](#): > > I would search for the lowest gearing (highest ratio number) available How would i know the cars gearing ratio tho? i have the app too, it doesn’t usually go into that much detail. I highly doubt it would say on there the gearing. But that is good advice, thank you ---

There should be an ID tag on the differential cover. Each rear axle listed on Ebay has a 3.31 axle ratio, might be difficult to find what you are looking for. ---
