Has anyone run stage 8's manifold bolts? Any info on how they are? Good bad? Any info would be great

 

You mean grade 8? Why not just get Dezod's?

 

no I mean stage 8, here is there site http://www.stage8.com/

and as for the dezod studs, my mani is 1 off, and thik as hell, I have asked about the dezod studs and can't get a real straight answer on the stud length, but I do belive that dezod studs a re actually just arp studs that are something like these ones

i see those being used on large garbage trucks all the time

 

The stage 8's seem for high vibration and critical applications only. Seems like overkill for a street manifold, drag maybe.

 

but, they are the same price as the street app. if not cheaper, so why not?

 

the dezod studs are between 1.75" and 2" didnt look at my tape measure that closely to tell u exactly but i just measure them cuz i didnt install yet.

 

yeah, but my thing is for 1/2 the price of these you can have locking manifold bolts that are just as hard if not harder then those.

 

I would be cautious of those bolts look how thin the heads are. What happens when a bolt gets stuck and you have to use force to remove it the head on those look very thin and weak? I don't care if it is harder bolts the head is still very thin. Why not have a machine shop machine the bolt hole faces on your manifold down just a small amount to accommodate the OEM studs and nuts?

 

Toyota_scion_tc, what are you talking about? These will not put anymore stress on the head then anything else will

 

I mean when you have to remove them the head has less than a standard bolt so when you have to remove it that will be the weak point.

 

I don"t know what you are talking about, lets say a standerd stud goes in the head 3/4" and these only go in 1/2", you are telling me the 1/4" these don't touch in the head will be weaker?

 

what he means is the HEAD of the bolt, the part you put a wrench on, is thinner than a normal bolt. Which could make it weaker, but to be honest I wouldn't worry. stage8 makes quality ____. My buddy runs them on his blown chevelle. I think it throws down a little more vibration/power/acceleration than any tC could throw at em. lol

 

I am not replacing the head bolts, just the exhaust manifold studs, the head stids and manifold studs are 2 differnt things

 

I was talking about the manifold. wtf and they dont make studs, they make bolts, that lock.

every reference in this thread of the word HEAD means of the actual bolt, not the head of the car, go bang your head against the wall untill that makes sense to you.

 

the head of the bolt is not thinner than any nut for any stud set out there, look at the picks on the site, then bang your head on something hard, like my fist and look again at the pics, these are hardend steel and they will be 5x's stronger then stock

 

It has a hollow head so it would thinner.

 

Thinner doesn't mean weaker, and I am ordering aset of these today, so I will let everone know how they work out

 

Its not immediately that you have to worry about it is having issues year down the road if you have remove them and they are seized. You will see the head being thinner will make it more fragile when removing them when they are seized and will be the weak point.

 

Ive been using Ace Hardware "hardware" on my turbo/manifolds for years. They do have high grade stuff. Make sure you get grade 10.9 or higher.
