Zone Offroad D2641 Replacement Steering Knuckle Box Kit Large Bore Passenger Side

The Zone Offroad D2641 is a replacement steering knuckle component box designed for the 2019+ Ram 1500 4WD equipped with Zone Offroad 6-inch suspension lift kits. This is the passenger-side, large-bore knuckle, specifically engineered for Ram 1500 trucks that came from the factory with 22-inch wheels (build codes WPM or WPZ), which feature a larger wheel bearing assembly requiring this wider-bore knuckle design.

Key Features:

• CNC machined construction for precision fitment and superior strength over OEM knuckles
• Designed to correct steering geometry and suspension angles after a 6-inch lift installation
• Large-bore design accommodates the larger hub bearing assembly found on 22-inch wheel-equipped Ram 1500 trucks
• Passenger-side component box — part of a multi-box knuckle kit (pairs with D2640 driver-side)
• Compatible with Zone Offroad 6-inch lift kits for 2019+ Ram 1500 4WD
• Manufactured and engineered in the USA

This knuckle box kit is a direct replacement or service component for Zone Offroad lift systems. If your Ram 1500 was not factory-equipped with 22-inch wheels, refer to the standard-bore knuckle kits D2630/D2631 instead. Replaces the factory steering knuckle to restore proper suspension, steering, and driveline geometry when running a lifted suspension system.
