Looking for aluminum 8.75” housing just giving it a shot

Why would you want one? Seems like the weakest thing you can put under power.

Im not too sure that piece belongs on a car.....maybe not the museum either, but if it were mine, I think it is best off "retired" to prevent potential damage. Coolness factor of "10", maybe even "11" lol.

I run them and have never had an issue with them.

I have a spare Mopar performance in the trailer with very
few runs that has been there for years. 4:56 Spool.

$2,450.00 Ready to run and that is a Bargain!

I have four, one is brand new, still in the box., I listed it here? a few months back, too pricey for most it seems.
Mopar stated it was 10% stronger than the typical 742 carrier.

Here is an out of production long ago Mark Williams 742 Alum carrier, it has rebuilt I believe 3.55 with an Auburn and a billet 1350 CM yoke, weight as pictured.
When I discovered there were a few Alum 8.75" aftermarket carriers around late 80's, I looked for years, and found this one in a for sale dragster that I had to buy to obtain it in NJ.
Early nineties I pleaded with Mopar to offer/build an Alum carrier, they blew me off and said there was no market. Decade later it was in their catalog

A side by side comparison, my others are installed.

Good to know. I weighed the center section of the unit I am running, 3.91, Sure-Grip, '489' housing and it came in at 73 pounds.

 

[GTX JOHN]

Mine is significantly lighter but it is a spool and some
other work!

I just weighed my new 9" aluminum center. In the bottom half of the box it came in (whole box around 5 lbs) It weighed 61.6, with 4,10 gear and a steel spool. I'm kinda disappointed it's not lighter, but I guess it has to be heavier than I expected, to be strong enough.

BTW I would guess the MW Alum carrier is a few lbs heavier than the Mopar Alum carrier, for reference check out the difference between the two in the mounting flange thickness.
