These High performance micro precision CNC Hardened Bevel Gears are super tough and rated to be 4 times stronger that stock powder metal ones. Highly recommended upgrade if you want to bullet-proof your differentials. VEKTA.5 requires 2 sets to complete. One set for the VESLA.5. SCM (Composite Steel) Material and Heat treated to HRC~40-45 for extra strength.
 
CNC machining allows for precise gear tooth profiles and tolerances.
Heat treatment increases the hardness and strength of the gears.
These gears are often used in high-performance applications.
