You might find this hard to believe, but a Ford 9" is lighter than a 12-bolt. It's even lighter than a 10-bolt.


I'm not sure if I would buy that or not. If that were true, then why would some NHRA Super Stockers and Comp eliminator cars run a 12 bolt (I've seen dragsters with GM 12 bolts...I've even seen Mopar S/S cars with GM 12 bolts. I guess it could also be less parasitic loss due to the pinion to ring gear position. But a stock 9" with an iron center section, I'm pretty darn sure the 9" is heavier than a 12 bolt.

Not having weighed either side-by-side myself, I surely could be mistaken though.

They use 12 bolts because they use less hp. The loss in friction out weight the loss you would have because of the weight.


I know that and that's why I stated the examples given. But that is somewhat old technology.

The current tech setup for lowest drag in a rear differential is a Ford 9-9 1/2" center section manufactured by Dewco. Ultra low drag, ceramic bearings, all the tricks at a cost of around $5k for the assembled center section.

Does anyone know off the top of their head how much a stock dash weigh? The only dash iv'e ever handled was one out of my dads '68 charger and it had to have weighed 30 lbs.

I just had my dash out and they are pretty light. I would say not more than 10 lbs. I am getting my new dash this weekend and can weigh it and tell you this weekend if you want to know.

Flatblack, the dash is a factory dash and it weighs in at 5 pounds empty with the glove box and the cluster.
