Product Description

The Eaton 14221-1 ELocker Differential is engineered to provide on-demand traction for Toyota and Lexus vehicles equipped with the Toyota 8" differential housing. This selectable electronic locking differential allows drivers to engage or disengage the locker via a dashboard-mounted switch, offering enhanced control in off-road conditions.

Designed for 3.91 and higher ring gear ratios and 30-spline axle shafts, the ELocker utilizes net-forged internal gears to deliver strength and durability necessary for off-road and recreational driving. The differential is compatible with rear-wheel and four-wheel drive configurations, making it a versatile upgrade for various Toyota and Lexus models.

Installation requires a clamshell-style differential housing, and the housing may need relief grinding to properly seat the electro-magnet. The ELocker is not compatible with vehicles equipped with Toyota's A-TRAC electronic traction control system. With Eaton's Roadranger support backing the product, the 14221-1 ELocker Differential offers peace of mind for drivers seeking improved off-road performance.
