GT350 axles!

[Voodooo]

Rear differential housing is 104.4 pounds dry!
HEAVY!!!! it would of been nice if ford used the aluminum housing for weight.

They made a significant number of engineering trade-offs specifically for cost when making this car. They did great keeping the price low, but that's also why it's 3850lbs instead of 3300. It wouldn't have gone over nearly as well at that weight but with an $80k MSRP I don't believe.

Each knuckle and bearing assembly are 20 pounds each

Correct but as a road course car they could of used the aluminum diff housing from the automatic GT

25.6 for left axle

 

[Voodooo]

18.2 for right axle

 

[Voodooo]

14.2 left lower arm with stock bearings and bushings

 

[Voodooo]

Camber links with hardware 5.2 each

Is it possible this is by design?

Or are you certain this is a manufacturing mistake.

I'll admit, I am ignorant on this. And my question might be foolish. But it seems too easy for this to me a mistake.

Stock toe links 3.050 each.

What are you referring to

Again, it is by design.

The aluminum differential housing wouldn't pass certain minimum durability standards behind a manual transmission with either the 5.0 or the 5.2 engine. Doesn't matter if the GT350 is being marketed as a drag car or not.

When the 5.8 GT500 was tested it was twisting the axle tubes in what engineers felt was a fairly robust axle assembly and as a result an extra rosette was added between the nodular center section and the steel axle tubes.

Cradle with oem bushing and wire harness only. The board was zeroed out. Weight of cradle is 64.3 pounds

Agreed!
The iron diff was used for strength and durability. If they could of. They would of used the aluminum. It's an existing part.

I understand how wheel hop works lol. I've drag raced for 25 years. Just never seen two different diameter axles used together. But I see your point. It's like a torque stick. (spring steel)

It's common on FWD cars to control torque steer. One of the front axles on my 2011 VW GTI was literally DOUBLE the diameter of the axle on the other side. :eyebulge: I wonder if that could be another reason for the different diameters here? (i.e. equalizing the torque to both wheels to compensate for differences from the asymmetrical differential?)
