Durable Forged Transmission Components for Automotive & Heavy Equipment Applications


Product Overview

We manufacture precision-forged gearbox housings and differential cases using high-grade alloys and new condition dies for superior dimensional accuracy. Our components are engineered for :

Automotive Transmissions (Passenger & commercial vehicles)
Heavy-Duty Differentials (Trucks, tractors, mining equipment)
Industrial Gearboxes (Wind turbines, marine propulsion)
Off-Road & Military Vehicles (High-stress environments)


Key Features & Benefits

1. Superior Forging Quality

  • New Die Sets for optimal dimensional consistency (±0.2mm tolerance)
