YOU ARE HERE / Billet Cases / GTR



Most sensitive and critical part of the GTR transmission and when the car launching is the Dif. case. When traction allows it and grip is too much maybe just one pass makes the Dif case split in half.

We offer life time warranty on this and we offer 3 types for different budgets. And most important of all its proven and tested.


Version 1 from billet aluminum (when we will be out of stock this item will discontinue)

Version 2 from billet aluminum and very lightweight construction and oil improving to the bearings.

Version 3 from billet magnesium ultralight racing construction and oil improving to the bearings



*Designed and manufactured under ISO 9001 certifications

Enjoy perfection !
