The R35 faces a serious problem putting big power to the ground: the factory front differential case flexes and destroys the front differential. That failure cascades — taking out the diff case, the engine block, the bellhousing, the steering rack, and whatever else it finds in the engine bay.
The Boost Logic Billet Front Differential Case is cut from a solid block of 7075 series aluminum for maximum strength while staying lightweight. Direct replacement for the OEM differential housing.
Optional upgrades (select above):
- Quaife torque-biasing differential upgrade
- Boost Logic billet front diff cover
- Sheptrans R35 front ring and pinion
