USA Standard Gear ZTNPMIM501 NP203 Transfer Case Part-Time Conversion Kit

The USA Standard Gear ZTNPMIM501 is a part-time conversion kit designed for New Process NP203 transfer cases. This kit transforms the NP203 from its original full-time four-wheel drive operation to selectable part-time operation, allowing drivers to switch between two-wheel drive and four-wheel drive as needed.

Key Features:

• Converts full-time NP203 transfer case to part-time operation
• Eliminates the internal differential assembly for direct power transfer
• Enables true two-wheel drive mode for improved fuel efficiency
• Reduces unnecessary drivetrain wear during highway driving
• Maintains both high and low range four-wheel drive capability
• Requires manual locking hubs for complete conversion (sold separately)

Benefits of Conversion: Converting your NP203 to part-time operation can provide improved fuel economy, reduced tire wear, and decreased stress on front axle components during normal two-wheel drive operation. The conversion allows you to engage four-wheel drive only when traction demands it, while maintaining the ability to run in standard two-wheel drive for everyday driving conditions.

Note: This conversion requires opening the transfer case for installation. Manual locking hubs must be installed on the front axle to complete the conversion and achieve full two-wheel drive functionality. USA Standard Gear produces top-quality transfer case components backed by extensive inventory and technical expertise.
