Need a couple quick gear opinions

[SVT-98-]

I know this has been gone over a million times, but my dif gears, and posi are toast. So should I switch to 4:30's over the previous 4:10's I had? Also the new gears from Ford Racing are made by motive (Italy). Are they any good?

Also I think Im going with a 03-04 Cobra traction lock w/31 spline Moser axles.


Thanks
Rich

4.56 ftw!

Thats' a little too much I think for my DD lol

Definitely go with 4.30s

As long as you need to replace the dif might as well upgrade, and the 03/04 Cobra is a good choice.

My installer likes FMS gears, but said if they are now being made by motive to stay away? Im not sure what to get then. :shrug:

I'd stick with the FMS....


And don't fear the gear.... if you plan on staying N/A... do the 4.56s...it doesn't make THAT huge of a difference.

No way do you want 4.56 for a DD.

If it was a couple times a week car/weekend warrior, then Id say go for it.

4.10 ftw

4.30s or 4.56s, don't be afraid.

**** it. 28" slicks and 5.14's. 488's at the least.....

Somebody needs to explain and prove why FMS is better than Motive.

4.30's ftw. I drive my car 80 miles a day with no problems.

Just get any 31 spline trac-lock and get the rebuild kit with the good clutches and you have pretty much the same thing as the 03-04 diff for cheaper. You can get a used t-lock out of an Exploder or F150 for under $100. As for gears I say get 4.30s.

If your staying NA go with the 4:30's. SC 4:10's. I got my car back today with the Vortech and the 4:10's kick ass.

I bought an Eaton 31 spline, Ford racing axles, and a Ford Racing 4:30's. Time for slicks this spring! By the way 4:30's are on National backorder. I found 1 set an Gene Evans Ford. Also anyone have any expirience with the Ford Racing gears from Park Ford which are ISF treated (their 4:30's are on backorder otherwise I would have bought them, but They have treated 4:10's in stock). Its some type of Vibratory finishing.
