These High-performance and precision CNC Hardened Bevel Gears are super tough and rated to be four times stronger than stock powder metal ones. They are a highly recommended upgrade if you want to bullet-proof your differentials. VEKTA.5 requires two sets to complete, one set for the VESLA.5. The material is SCM (Composite Steel) and Heat treated to HRC40-45 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.
