Hardened Reverse Gear Shaft

This shaft has been heat treated to make the surface extra hard. The hardening process gives the shaft excellent resistance to wear and scoring. The product is used in vehicles that get heavy use or frequent reverse shifts. You get a shaft that does not develop grooves from gear teeth contact. The hardened surface also resists damage from debris in the oil. This shaft is recommended for trucks and other commercial vehicles. Many fleets use this part to reduce their maintenance costs. The hardness is measured and confirmed with a special testing machine.

The outer layer of this shaft is much harder than the inner core. You get a product with a tough surface and a shock resistant center. This combination gives both wear resistance and impact strength. The shaft has been tested to confirm the correct case depth and hardness. It is ground after hardening to restore the precise dimensions. The product has a smooth finish that is free from any heat tint or scale. This shaft can last two or three times longer than standard shafts. You will find it is worth the higher price for demanding applications. The part has been proven in many heavy duty gearboxes.
