Default how strong is factory stock 9" case

Im was looking a third member with a factory case with spool and 4.11 gears.
like seen here


I called to get it and they said i would brake it for a fact? Then why do they offer it for Circle Track, Street,Strip on there site? my car only has 413whp and has been fine with the 10 bolt for 129k miles. only problems ive had with it is bolts coming loose. I have had many 1.6 60 fts on it so i would this this stock 9" stuff would be way stronger the 10 bolt. What r your thoughts?

They're right, you'll probably break it. If you do a search on here you'll see pic's of ones that have been broken on 400 to 500 rwhp cars. Bob

I think you'll be okay on all season street tires. Bob
