Default Fab reared housing vs Aluminum reared housing

Walking around the pits I’ve noticed more fabricated reared housing than an aluminum housing on the 4link dragsters.

Is one better than the other or is this more of a cost/ease of manufacture for the chassis builders.

Thanks

I have seen some of the fabricated housings break, but never seen one of the strange rear ends come apart. you can break a gear in either, but I chose the strange one for the strength. Super Comp 321X

I'm guessing that once a chassis builder has the patterns and the jig he can build a fabricated housing cheaper than he can buy a Strange ,Mark Williams or aerospace housing.
The only concern I could see with the fabricated housing is the number of welds that could crack and or leak. You could weld attachments to a fabricated one which you cannot or should not do with the cast housing.
In my 30 years of racing I haven't seen either fail in a dragster

I believe the cast Alum housings are stronger but are heavier. I have a Ed Quay XL Dragster and they offered them standard w/ a comp engineering fab housing standard but offered a MW modular housing at extra cost. My Car has the Fab housing and no issues w/ it. Guess its a more cost effective way to keep cost down but sometimes money isn't an object to some
