What is the difference than to just buy the brackets and put them on any 9'' that will fit or aftermarket? I know that a aftermarket you can get anyway you want it. But is there any weight differences between the two? And I've done some searching and seen where alot people said that they where hp robbers.And I see why they way a ton. Anyone done the 9'' with just buying the brackets?

 

i dont see why there would be very much weight difference

any real weight difference would be in width difference between axles, and type and model of carrier

the housings themselves are light, around 40lbs

the carrier and gears are what weigh something

welding the brackets on yourself is the way to go if you have a welder and can find a narrow enough axle to do it to

i dont know what you would use to weld steel brackets to the iron center housing for the TQ arm and such

someone know ?

 

If you just stick the brackets on some stock POS, then you end up with..... a stock POS with some brackets welded on it. If you buy an aftermarket one, you can get a strong center section, a better housing, and so on; in short, something VASTLY better than some stock POS.

The 9", as it came from its mfr, is a pile of junk. It's weak; nowhere near as strong as a GM 12-bolt (car version). The 9" itself, out of the junkyard, isn't what's so great; it's its usage as a PLATFORM that you can build on. It's a good design, from the standpoint of how it goes together. Quick to change ratios, doesn't use C-clips, and the parts are big enough that you can make replacement ones that are far better than the best you'll ever find in a junkyard.

If all you want is some kind of bragging rights ("yeah, I'm SO BAD, I've gotta have a 9" in my car") then do the junkyard and bracket thing. On the other hand, if you want something that's actually better than what came in your car, go aftermarket.

Also, stock ones are notorious in these cars for creating pinion angle problems. One of the benefits of an aftermarket unit is that it has a chance of ACTUALLY fitting the car somewhat.

 

I think Moser still sells the torque arm mount bracket. You cut all the other brackets for LCA, shocks, panhard bar off a donor diff and weld them onto a 9" or if you have any kind of fabrication skills, you make your own. It's the torque arm mount that doesn't make using a junkyard diff easy.

9" diffs also come in many different lengths with different pinion offsets, axles sizes, bearing ends and brakes. You need to know exactly what you're looking for before grabbing just any 9" housing.

My "factory" 9" diff got my into the high 9's. Factory housing and center section. Strange spool, unknown gear brand and Strange 31 spline axles. I welded ladder bar brackets on to eliminate the torque arm. I now have a narrowed diff and a 4-link under the car.

Normally by the time you're don't fabricating and modifying, it can be cheaper to just buy an aftermarket bolt in diff.

 

Yea I found a company that will sell a housing to fit the camaro for $650 to my door or $950 complet.I dont know if the comple comes with the 3rd member but I all ready have it.

 

$950 will include the axles with bearings and nothing else. A complete, ready to bolt in and go diff will be around $2500

Just make sure the axles are in the same spline count as the carrier you currently have.

 

Yea they are 31 And it includes :axels,axel bearings,studs,TA braket
