Zumbrota RTC4417F-1 Transfer Case

The Zumbrota RTC4417F-1 transfer case is engineered for durability and reliability, tailored specifically for 4WD applications in select Ford and Lincoln models. Each unit undergoes meticulous rebuilding processes to meet high-quality standards, ensuring optimal performance in demanding conditions.

Construction and Quality Assurance

Crafted by skilled technicians with over 150 years of combined experience, the RTC4417F-1 is restored to like-new condition. Each transfer case is rigorously inspected and tested for potential wear issues, including:

• Cracks and structural integrity
• Stripped threads and shaft warping
• Gear wear and chain stretch

All internal components, including bearings, seals, and viscous couplers, are replaced to ensure longevity and reliability. The hydro-blast rinse and sandblasting process guarantees a clean, OEM-like finish, while a proprietary deep cleaning method enhances overall performance.

Testing and Shipping

Before leaving the facility, each unit is spin-tested to confirm shiftability and noise levels, ensuring it meets the performance expectations of demanding drivers. To protect against damage during transit, the RTC4417F-1 is packaged in high-density plastic totes.
