Motive Gear MG620001 Rear Transfer Case Housing NP149/246/261LD/261HD/263LD/263HD

The Motive Gear MG620001 is a replacement rear transfer case housing designed for GM NP/NV-series transfer cases, including the NP149, NP236, NP246, NP261LD, NP261HD, NP263LD, and NP263HD. This rear case half directly addresses a well-known design flaw in the original New Process/New Venture housings where the internal pump tends to migrate and abrade the aluminum case wall, eventually causing leaks or catastrophic case failure.

Motive Gear engineered this housing with reinforcement around the pump area, eliminating the need for a separate pump saver insert (BRNY). The result is a more durable replacement that outlasts the factory unit and resists the pump-knock wear that commonly plagues high-mileage GM trucks and SUVs.

Key Features:

• Reinforced pump area prevents pump-rub wear and case leaks
• Both sensor ports come pre-threaded and ready for installation
• Tailshaft bushing pre-installed at the factory
• Output shaft needle bearing pre-installed for a complete, ready-to-install assembly
• Compatible with NP/NV 149, 236, 246, 261LD, 261HD, 263LD, and 263HD transfer cases
• Direct OEM replacement fit — no modifications required
• Manufactured to meet or exceed OEM specifications

What's Included:

• 1x Reinforced rear transfer case half (housing)

Motive Gear products are engineered for specific applications and manufactured in state-of-the-art facilities, with rigorous quality control processes to ensure proper fit, performance, and longevity. This housing is a trusted choice for professional installers and DIY builders tackling transfer case rebuilds on GM trucks and SUVs.
