7 1/4 rear strength

I beat the crap out of mine. In fact it leaked oil so about 5 or 6 years ago I just stopped putting oil in it. I beat that thing hard. I tried to break it on purpose a few times. Behind my drag race 360 it got its *** kicked on a regular basis a never even flinched.

When I pulled it out a few weeks ago I kinda wanted to open it up and see what it looked like but I was just to busy and the scrap guy picked it up before I got around to pulling the cover.

Mine musta been a sure grip tho or it welded the spiders its self cuz it burned both tires.
Dont think it would have lasted out the parking lot with my new slicks tho
