They are machined from a billet of Duraluminium (EN AW 7075 T651) to provide significantly higher strength, durability and resiliance than even other Aluminium shells. 

These shells come with a Quick-Change Spring Guide and all necessary screws. 

The bearing holes are 8mm in diameter.


Technical expertise is required to install and tune this garbox. 
Screws should be torqued down to 1Nm.
