JA82 Rear Differential
The JA82 rear differential supports vehicle programs that require reliable rear-axle power distribution, defined mounting interfaces and stable operation on demanding terrain. Engineers should confirm the target ratio, torque capacity, input direction, side-shaft connection, mounting geometry and differential or locking function before integration. Vehicle mass, payload, tire size, gradeability, ambient temperature and shock-load conditions influence validation requirements. Zhejiang Jessica Transmission provides OEM support from early application discussion through drawing review, samples, testing coordination and serial production.
