In the C6 ZR1, the left half shaft is thicker than the right.
The left half shaft diameter is 40 mm and 33mm the right
Does anyone know why?

When they were developing and testing the ZR1, they had issues with axel hop. The engineers tracked this back to a resonance issue.

The Asymmetric shaft diameters were used to keep the half-shafts from establishing a resonance, thereby reducing axel hop.

Magneto-rheological shocks help mitigate this as well. When drag-strip launch detected, shocks provide zero jounce and 100-percent rebound stiffness to encourage squat and minimize wheel hop.

Thank you. Happy with you. Know everything

Do you know if these features were included in the Z06's with the Z07 package? Pretty sure they have the same half shafts but not positive on that or the magneto shock functionality.

Axles are the same. The ZR1 got a thicker differential case (different than the z06, and $1300.00 more), the axles mentioned above, different gear ratios in trans, harder steel gears in trans etc. I remember reading somewhere that the shock functionality is in the computer, and the shocks are the same as any F55 car.

Yes, Z07 cars got CCB's and mag ride.

Hello,

Excellent question! The purpose is to cancel wheel hop and is accomplished by utilizing a half shaft that weighs 1/2 the weight of the other half shaft.

The ZR1 is a marvel of engineering.

I was specifically asking about the ability for the car to notice a drag launch and change the magnetic shocks accordingly. Sorry. Wasn't very clear. Just curious because I have a Z07, Z06 and get plenty of wheel hop on the drag strip. Not so much on the street though.

MTPZ06

To my knowledge, its the same system.

I have a 2011 Zo7 and I get plenty of wheel hop so not sure it's engineered out.

Mr. Gizmo

all z06's 2009 to 2013 have these axle features. In 2009 the Z06 benefited from these upgrades because of the introduction of the zr1

So what would need to be done to put these axles in an 06 Z?

double06

You can not put them in an 2006Z because the hub spline is a 33 count on the outer edge. The 2006-2008 are 30 spline. You would need to get some 33 spline outer bearings with the early electronics on them too as the electronics changed in 2009.

For what it would cost to adapt, especially because of electronics, it just is not feasable. You can buy a complete set of DSS 1500+hp axles/hubs for less than it would cost to convert an early car.
