Product Description

The Eaton 14215-1 ELocker is a high-quality selectable locking rear differential designed for Toyota's 8.2-inch rear axle with 30-spline shafts. Under normal driving, it operates as an open differential, allowing wheels to rotate at different speeds for smooth cornering. When additional traction is needed - such as off-road terrain, snow, mud, or heavy towing - the driver activates the electromagnet switch to lock the differential, sending full torque equally to both wheels.

This unit fits multiple Toyota models listed above (4Runner, FJ Cruiser, Land Cruiser 150 series) through **2025**, for all gear ratios, assuming correct axle spec (8.2-inch housing, 30-spline shafts). Some '09-'18 Land Cruiser 150 vehicles may have alternate output shaft/hub setups (33 mm output shaft or manual locking hubs) which require ensuring compatibility. Housing may require relief grinding to properly seat the electromagnet. It includes all necessary wiring and control hardware for installation.
