Q840 Front Differential
The Q840 front differential supports off-road vehicle drivetrain programs that need stable front-axle power distribution, clear integration interfaces and dependable operation. Application engineers should review ratio, torque, input direction, mounting geometry, side-shaft connection, vehicle mass, tire size and the intended terrain before final selection. Thermal conditions, lubrication, impact loading and gradeability should be included in validation. Zhejiang Jessica Transmission works with OEM and industrial customers on technical clarification, drawings, samples, testing and production supply.
