rear end

Gear Oil will be the 75W 140, which ever brand you like. You'll need a pinion bearing, differential seal and crush sleeve. Othere then that, you should be good to go. Buy Ford Motor Racing Gears and you wont have to worry about installing new shims. If you purchase another brand, there is no gaurantee. Oh, make sure you have some paint on gear marker to check the gear meshing.

alright sounds good and if i did by them there a OEM set on ebay for like 80 bucks plus shiping there new to so im looking in to thouse right now

 

[GT400SC]

I have 4:10s in my 05 automatic.

What a wonderful world it is!

1. pro 5.0 makes a 3.90 gear.... and 2. why you worried about MPG? did you buy a mustang to save gas????? 4.10's

 

[GT400SC]

3000 rpms at 75 mph!

OH YEAH!!!!!!

 

[LaughingGT]

no i dident if iwant ed to save gas i woudl have bougt a v6 and i just want a diffrent gear seting and i dont want to go all out i want to work my way up and find whats a good combo and that way i will also have back ups

 

[02gt]

i would say go with a 3.90 then.... i dont think you'll ever win the battle of MPG so make it count.

 

[GT400SC]

Well, then you will get a lot of experience changing rear gears and you'll probably end up at the same place.....4:10s.

 

[Foxman]

the wiork has been done for you already 4:10s for the win

 

[LaughingGT]

they are all the same price on ebay for all of them OEM brand new

 

[02gt]

when you say oem do you mean ford racing???? those are the good set.

 

[GT400SC]

I got my set (Richmond) with all the bearings, seals, gasket and new bolts for $100 (Brand New) on Craigslist.

There are deals out there! Be patient and shop well!

 

[02gt]

[LaughingGT]

well this wansent going to be anytime soon just lookin in to it i havent even instaled the new x pipe yet hahaha but just good to know all this what gear do u hit 75 at GT

 

[GT400SC]

My trans is automatic. Overdrive

 

[LaughingGT]

i got an auto as well

 

[Mustangcwo]

i got an auto as well

Then I suggest you forget anything lower then a 4.10. Any lower gears will not create much gain. The 4.10 gear is optimal for matching engine rpms to horsepower during shifting. This has been proven by multiple sources and comes highly reommended by yours truely and 5.0 magazine....just ask GT400SC.

 

[LaughingGT]

well looks like i will start seting myself up for that thanks agin for the inputs

 

[LaughingGT]

when you say oem do you mean ford racing???? those are the good set.

idk the site said OEM i dont knwo if it means ford raceing or not but there brand new for an 8.8 rear end

 

[LaughingGT]

well for 168 bucks i can get ford racing 4:10's

and everywere i have been reading on says autos have better luck with 4:10's. it dosent realy kill ur MPG in town it will dampen them slightly on the highway but not to bad anyone in here notice that ???
