Using a super light duralumin (A2014) as its main material that the strength has increased by 50% and hardness by 30% (over previous version). This change in material has allowed the design change that has also allowed the unit to be substantially lighter (10% less load on RB engines) and increasing the engine reliability and power.
Gear section is nickel plated for surface hardness increase (Hv: 350 → 500 (compared to older version)) to withstand strengthened timing belts and any foreign objects that may get caught between the gear and belt.
