Yes, another rear end question lol.

OK, so I was looking through some older posts in here today when I (think) realized something that doesn't make sense.

OK, most of us know what the anti hop bars are. I currently have a set on my 7.5 rear. Now, correct me if I'm wrong on any of this.

- only meant for use on the stock rear ends
- not good for 350ish HP or more
- not to be used on any aftermarket rear because they are already designed to relocate the upper arms

So, what is the best thing to do in a high HP application? Run an 8.5 without the anti-hop bars, or run an aftermarket rear even though it has the upper mounts relocated? Or... is that why so many of the race cars I see run the B-body rears with the special trailing arms?

I'm not planning a swap any time soon. I'm just curious. 🙂

No, if the rear going in is a "bolt-in" replacement, you can use the bars. Some aftermarket rear upper ears are sligtly lower then stock, so they would be a good thing in that case.

Guys have gotten deep into the 9z with them but they are the exception to the rule. 400/500 seemd to be the tipping point.

See above, they are all not the same. If the replacemnt already has them raised then no, stock or lower, then yes assuming you are within the hp range

How much HP?

Run an 8.5 without the anti-hop bars, or run an aftermarket rear even though it has the upper mounts relocated?

Or... is that why so many of the race cars I see run the B-body rears with the special trailing arms?

Bbody rears in Gbodies? are you sure ? or do you mean Abody?

My 600 hp Cutlass is a stock width/mounting point 68 abody 12 bolt.

My 350hp Wagon has a 8.5 with anti-hops.

Hope that helps.

Oops, yeah I meant A-body. I'm not gonna be in the market any time soon. But have been thinking a lot about what rear to go with when the time comes.
