How strong are stock rear ends?

[steve04cobra]

Just curious how strong the stock rear ends are and if it is recommended to strengthen the rear, i don't plan on putting an excessive amount of hp to the car and if it is recommended where do i start. thanks in advance

They're decently strong, but have a tendency to hop and and can break things in the process.

Read this article for excellent advice and ways to fix it.

so what can i do so that i wont break anything? maybe an irs brace or control arms?

An IRS brace is a really good start. Since it's an IRS leave the control arms alone. Lowering springs and subframes will help, as well as replacing all the rubber bushings.

Also read this. Probably the best post about ways to fix Ford's shortcomings with the IRS.

Keep in mind you can break halfshafts on a stock car under the right conditions.

Conversely, if you don't beat on your real end and most importantly, get out of it when it wheelhops, you should be OK. Guys are running twin screws with the stock rear ends and have made tons of track passes without breaking anything.

An IRS brace is all I plan for the rear end.

you can break ANYTHING if you try hard enough.

Having a car that doesn't wheelhop does NOT mean the differential housing is stabilized! :idea: A differential housing that is not stabilized is just as likely to pop a halfshaft as from wheelhop!:read:

FWIW

I have 18,000 miles on my car, and I have wheelhopped BAD probably over a hundred times. My rear end is still holding strong. That doesn't mean it will remain that way, but heck,,,I've made about ten track passes, and I've been running Nitto drag radials on the street now for a long time. So far, so good...:thumbsup:...!! See sig for mods.

haha i love it when people beat up on their cars. i use to wheel hop really bad (verts are horrid) all the time. The delrin bushings (accobra) cured 95% of all the hop, and that little 5% is very mild in comparison to the way it was stock! 60,000 miles and still going strong.

Only as strong as it's weakest link, yes you should stregnthen it:
FLSFC
IRS Brace
Tires

That would be a good start and you can progress from there. There are planty of kits available to fix the other imperfections with the reasr end. You may want to take a look at AC427cobras kit as well, I hear great things about it.

Otherwise if you feel the rear hop, get out of it.

get the billetflow brace, it could save you lots of repair money in the long run. this should be the first thing you do to the rear end. i had mine put on when having the differential resealed and the fit was great. do a search and you will find lots of info on it
