Vehicle Fitment

• 2003-2025 Toyota 4Runner (Front, Independent Front Suspension, 4.0L V6)
• 2005-2023 Toyota Tacoma (Front, Independent Front Suspension, 2.7L I4 & 3.5L V6)
• 2005-2014 Toyota FJ Cruiser (Front, Independent Front Suspension, 4.0L V6)
• 2002-2009 Toyota Land Cruiser Prado 120 / 120 Series (Front, Independent Front, 4.0L V6)
• 2010-2018 Toyota Land Cruiser Prado 150 / 150 Series (Front, Independent Front, 4.0L V6)
• 2003-2009 Lexus GX470 (Front, Independent Front Suspension, 4.7L V8) [if 8" IFS 30-spline, check housing & bearing variant]
• 2003-2024 Lexus GX460 (Front, Independent Front Suspension, 4.6L V8) [check 8" IFS & 30-spline compatibility]

Fitment Notes

• Only fits *clamshell style housing.*
• Housing may require **relief grinding** to properly seat the electromagnet. 
• Fits only 8" IFS front axle with **30-spline** axle shafts.
• Ring & pinion gear ratio must be **3.73 or numerically lower (3.73 & down)**. 
• Does *not* fit 8" IFS with 3.91 & up gear ratios - other Eaton models (e.g. 14221-1) cover those. 
• Some models (e.g., GX470, GX460) may have multiple housing & bearing variants; confirmation advised.

Features

• Driver-selectable electronic locker - open under normal conditions, full-lock on demand. 
• Net-forged internal gears for high strength & durability. 
• 30 spline axle shafts, compatible with 8" ring gear IFS Toyota front axles. 
• Works with 3.73 & down gear ratios - tight clearance for numerically higher gear ratios. 
• Clamshell style housing design for structural rigidity and easier mechanical integration. 
• Sealed electromagnet locking mechanism, relatively low maintenance. 
• OEM-grade materials, designed for trail, rock crawl, towing or off-road hardships.
• Weight ~23.04 lb for the assembly - manageable for front axle replacement.

Product Description

The Eaton 14219-1 ELocker is a front selectable locking differential built for Toyota 8-inch independent front suspension (IFS) applications with 30-spline axle shafts. Under normal driving, it behaves like an open differential for smooth turns, tire longevity, and lower noise. When traction is lost - on rocks, mud, snow, or steep inclines - the driver flips a switch and the electromagnet locks the differential, sending full torque equally to both front wheels.

This product is engineered specifically for front IFS spindles of the Toyota models listed above, provided the ring & pinion gear ratio is 3.73 or numerically lower (i.e. 3.73 & down). It will *not* function properly with higher numerical gear ratios (3.91 & up), nor with housings not matching the clamshell style or with different bore/spline counts. For 2025 models, fitment is confirmed through the Eaton application guide up to 2025 for Toyota 4Runner and Tacoma front IFS with the stated specs.
