The front differential lock dedicated for TOYOTA HILUX VIGO, 4runner and Fortuner is a core four-wheel drive transmission component for hardcore off-road vehicles. Designed for unpaved road crossing, complex terrain escape and heavy-duty off-road driving, it complements the front-wheel locking function and improves the overall linkage performance of the four-wheel drive system, suitable for outdoor exploration, mountain driving and field operations. The stock open front differential tends to cause power interruption when a single wheel slips or hangs in the air, and this assembly perfectly solves the problem and enhances all-terrain adaptability.

The assembly adopts a high-strength forged housing with solid structural performance and outstanding impact and pressure resistance. It effectively protects internal gears and transmission structures from external damage caused by gravel impact, road jolts and chassis grounding during off-road driving. The precisely processed internal gear set is professionally heat-treated with tight meshing teeth and smooth transmission. It maintains stable transmission state under high torque output in extreme conditions such as heavy-load climbing and muddy sand escaping, avoiding transmission abnormal noise and gear jamming.
Featuring a mature and reliable mechanical structure, the differential lock can lock the power of the left and right front wheels on demand to realize synchronous driving and eliminate single-wheel idling, greatly strengthening front-wheel grip and vehicle escape capability. It works normally on urban paved roads to retain flexible steering and smooth driving, balancing daily driving comfort and professional off-road performance.
With an exquisite sealing structure, the assembly prevents the invasion of silt, sewage and dust, keeps internal lubrication stable, and reduces component wear and corrosion for longer service life. Manufactured in strict accordance with original vehicle standards, it supports lossless in-situ replacement with easy installation and maintenance, serving as a reliable accessory for chassis upgrading and four-wheel drive performance optimization of the above models.
