Default Weight difference 9inch vs 8.8?

Trying to figure the weight difference between a fully built 9 inch and an 8.8 for fbody use.

Does anyone know the total weights of these two setups?

I was going to build an 8.8, but i think im gonna change my mind. Is weight any reason to still go with the 8.8?

While I don't know how much a fabbed up 8.8 would be, I can't imagine it being much lighter than a 9" that's been fitted with a lighter weight center section. There seem to be quite a few options for shaving pounds from a 9" rear...not so much for the 12-bolt, 8.8 or S60.

If your worried about weight. You can buy a fab axle and housing/Torque arm package from Midwest chassis and assembly your own 3rd member if there is a tight budget.

Well you could buy a new or find one used aluminium case a used spool and buy new bearings and gears. Or you could go cheaper and find a stock ford case which I wouldnt recommend but have had friends that have done it.

Moser fabricated housing/axles/torque arm package. if you added an aluminum center section to his package, it usually comes out to the same weight as the 10 bolt. This package ships out just two days after it is ordered!

Take a look at the above link for my very low Moser center sections prices. Thanks. Bob

What bob said. You'll want a Fab 9 and an aluminum center section. It'll be lighter than an 8.8 by far. If you want "cheap" you'll probably have to break out the welder yourself. The 8.8 is heavier than the 10 bolt, but lighter than a nodular 9"

When it comes to cutting weight back in a housing and center section I am most likely your man to go to. The problem is there is no cheap way to cut back weight. Certain things can be done when putting our package together that do not cost extra however.

We can put together a lighter fabricated nine inch than anyone else can all while still keeping it street friendly. (As street friendly as a spool may be) You have to keep in mind some things will have to be sacrificed to really get into cutting weight back.

I have a chassis with a built 8.8 with everything I can do to cut weight off and out of it and will be swapping it to one of our housings next year because after doing the math I should be able to save a few more pounds with our fabricated housing.

Comparing an 8.8 to a 10 bolt with comparable components the 8.8 would be heavier. I had an 8.8 we was building for a local customer and weighed it but can not find the weight off hand.

We have a few customers right now going the extra mile with weight savings and trying for the N/A records. We have put a ton of thought into ways to help these guys out.
