Description

The Crown Automotive Differential Gear and Pinion (MPN: J0945345) is a reliable gear upgrade designed for dependable power transfer and drivetrain efficiency in off-road and on-road conditions. It is specifically built for use with a Dana 30 front axle and includes all necessary components to restore differential function to OEM standards. This gear set is made from high-quality materials and engineered to withstand tough driving conditions. The components feature a strong build and a precision-machined surface for seamless meshing and performance, meeting or exceeding OEM specifications for proper matching with your axle's internal components.
