Interest in helical gear differential

The Back Story: I am trying to develop a limited slip differential solution for the following Jaguars with DANA 44 AdvanTEK rear axles.

• F-Type, F-Pace, XF
• possibly some XE and XJ models

The solution would be based on a helical gear differential carrier, which is also called a Torsen® or TrueTrac®. This type of LSD has the following advantages over traditional friction plate types.

• Maintenance free as there are no clutches or springs
• Quiet operation with no clicking or ratcheting mechanisms
• Both forward and reverse torque transfer capability
• Instant torque transfer

I also need to learn a bit more about the XE and XJ rear axles. If you have an old one or access to a parts axle, please contact me. There are a few key dimensions that will instantly tell us if it is compatible.

Thanks, Herman

 

Dear Herman,

Did you manage to achieve something regarding this?

Yours sincerely,
Luka Bilić

 

Luka,
Yes, I had great success with the fist batch of 10 units that I commissioned from Quiafe.
These are all in Jaguar Forum member's cars.
And the results have been very positive.
See the details over at the X152 threads.

This is amazing!

I would love to consider these for my AWD jaguar XE.
Do you think that friction modifier based on PAO functionalized graphene oxide monosheet could improve the helical gear differential life and performance?
