Does the LX570 have a locking differential?
The LX570 does not include a traditional locking differential. It relies on a full-time four-wheel-drive system with a center differential that cannot be manually locked, instead leveraging electronic traction features to maximize grip in challenging conditions.
How the LX570's drivetrain handles traction
The LX570’s four-wheel-drive setup is designed for on-road comfort with off-road capability. It uses a center differential (a Torsen-type design) that is always engaged, so there is no standard user-accessible lock switch for the center diff. When conditions get tricky, Lexus/Toyota’s electronic systems come into play to optimize torque distribution rather than physically locking the axles.
What qualifies as a locking differential
A locking differential physically forces the two wheels on an axle to rotate at the same speed, which helps when one wheel has little traction. The LX570 does not offer a conventional locking differential for the center (or a dedicated rear axle locker) as a selectable feature in its typical configurations. Instead, it relies on traction-management electronics and a non-locking center diff to improve grip.
For off-road performance, the LX570 employs a suite of systems that compensate for the absence of a manual diff lock:
- A-TRAC (Active Traction Control): Brakes individual wheels and redistributes torque to maintain traction on loose or uneven surfaces.
- Crawl Control: Maintains a steady, low speed to help the driver focus on steering over rough terrain.
- Multi-Terrain Select (MTS): Offers modes tuned for mud, sand, rock, and other surfaces to optimize torque and braking.
- Kinetic Dynamic Suspension System (KDSS): Improves wheel articulation by adjusting anti-roll bars, helping keep tires in contact with the ground.
- Two-speed transfer case with 4H/4L gearing: Provides low-range gearing for steep ascents/descents and technically challenging terrain.
These features collectively enhance grip and controllability in off-road conditions without a traditional locking differential.
Practical notes for LX570 owners and buyers
Across its production span, the LX570’s approach to traction has remained rooted in electronic aids rather than a selectable locking differential. For buyers seeking a vehicle with a true locking center or rear differential, alternative models in the Toyota/Lexus lineup or other brands may offer that specific capability. In the LX570, off-road competence comes from A-TRAC, MTS, KDSS, and low-range gearing rather than a manual diff lock.
Summary
The LX570 does not feature a traditional locking differential. It uses a center differential with mechanical and electronic traction aids—most notably A-TRAC, Multi-Terrain Select, and Crawl Control—along with KDSS and a low-range transfer case to improve grip and control off-road. For drivers who specifically require a locked differential, this model line does not provide that option, and alternative vehicles would need to be considered.
