Hey so i own a 2006 ford mustang v6, i was thinking of buying some 4.10 gears and installing them for better acceleration. I’m trying to figure out how much it would cost overall. -4.10 gear kit from ford racing = approximately $300 -Mechanic installation = $550 (i called a couple places best i g…

Is that 4,10 gear kit for the specific differential installed on your Mustang? Usually V6 cars have lighter duty rear ends than the ones installed on the V8 models. A\lso, your gas mileage will suffer and the car will be miserable to drive on a trip.

[image] Mustangman: Might be cheaper to just switch complete rearends if you can find one off a wrecked V8 car honestly didn’t even know that was possible, il research it. Only thing is, i believe my mustang has 3.55’s so i don’t know if changing to 3.73’s would make enough of a difference t…

Your V6 Mustang has a smaller axle than the V8s… a 7.5 inch ring gear, I think. The V8s 2005 to 2014 have 8.8 rearends.

What are they doing now? Adopting Benz nomenclature for the models?

These days with everything having overdrive, and computer controls, Changing the rear end gears out doesn’t make a huge difference overall. In the OP’s case, going from a 3.31 to 4.10 would likely result in a slight improvement in fuel economy in local driving, and a slight decrease in purely high…

No, it’s just the platform names for various generations of Mustang 79-93 = Fox 94-98 = SN 95 ( glorified Fox) 99-04 = New Edge ( still a glorified Fox) 05-14= S197 15-23 = S550 2024+ = S650 ( More of an evolution of the S550, supposedly).

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.
