9" Aluminum Through-Bolt Cases.

9" Aluminum Through-Bolt Cases.
Trying to decide.....
Nodular, S casting, aluminum through bolt, or....WHAT?
I like the idea of keeping it as light as possible, but are the aluminum through bolt cases strong enough? Are they susceptible to pinion deflection? How's gear wear in the aluminum case? Also, do the aluminum cases tend to be more noisy than the iron ones?
What else.....Do the aluminum 9" cases require grinding so that they clear the rear torque arm mount?
All I want is a rear that is an easy bolt-in, is durable, light-weight, quiet, and inexpensive. (OK, just kidding with the "inexpensive" part!)

I probably got carried away here with too many pictures... We have not had a problem with the Moser aluminum cases, and the torque arm bolts right up without any modifications. Bob

hear nothing but good things, I'll be home in about 1 week (in the desert) so I'll be ordering it from EPP. (BOB) here soon. I'll be ordering aliminum casing so I think you'll be alright .

Susceptable to flex? Uhm... I dont understand the mechanics of your question. But, the answer to this is no (with the exception of the "lightweight" cases for use in chassis 2500 lbs and under). The alloy cases have increases in thickness in the areas of question to combat any rigidity issues due to material.
Gear wear? Dont understand this question either. What makes you think it will wear more or less? The answer to this is... that there is/will be no difference... so, no.
Gear noise? What makes you think it will make more or less noise? The answer to this is as well... that there is/will be no difference... so, no.
I think it would be an excellent choice to use a thru bolt case... as long as it is a good thru bolt case. Some are better than others, but for street applications... all but the "lightweight" cases will do just fine.

from Moser's website: "Moser Aluminum Cases are made of 356-T6 aluminum with 7075-T6 aluminum caps and billet steel adjusters, and they feature a super strong through-bolt design to give the case increased strength and decreased ring gear deflection common in most aluminum case designs."

"Strange lightweight aluminum case is for applications where weight is crucial and gear set life is not a issue."

Still lots of choices out there...Currie, Mark Williams, Moser, Ford Motorsport, Strange...what to do
