Eaton ELocker Service Kit - Electromagnetic Locking Differential Maintenance

Eaton ELocker Service Kits deliver the genuine replacement components required to properly maintain and restore the performance of Eaton's electromagnetic locking differential system. Engineered to Eaton's exact specifications, each kit provides authentic parts that keep the ELocker functioning as designed—delivering reliable, driver-controlled traction on demand.

About the Eaton ELocker System:

Under normal driving conditions, the ELocker electromagnetic locking differential performs as a conventional open differential, preserving everyday ride quality, tire wear, and fuel efficiency. When an obstacle is encountered, the driver activates a dash-mounted switch, engaging the electromagnetic mechanism to lock the differential and capture 100% of available torque, sending it equally to both driven wheels. A second flip of the switch deactivates the unit to resume normal driving. The ELocker is engineered with net-forged gears for added strength, making it well-suited for off-road, rock crawling, trail riding, and towing applications.

Service Kit Types Available:

• Gear Service Kits — Restore worn internal gear components including side gears, pinion gears, thrust washers, and related hardware to factory specification
• Locking Mechanism Kits — Replace critical engagement components such as push rods, wave springs, lock-up plates, ball ramp sets, ball bearings, preload springs, thrust bearings, bearing races, and retaining rings
• Stator / Armature Kits — Rebuild the electromagnetic actuation system with a replacement stator assembly, bearing race, thrust bearing, and retaining hardware
• Universal Wiring Kits — Replace the dash switch, fuse and holder, relay, and associated wiring components; the ELocker wiring harness is universal and fits any vehicle

Key Features & Benefits:

• Genuine Eaton Components — Authentic parts engineered specifically for the ELocker system, ensuring correct fit, form, and function
• 100% Torque Lock Capability — The electromagnetic locking mechanism delivers full available torque equally to both driven wheels when engaged
• Open Differential Efficiency — When disengaged, the ELocker operates as a standard open differential, preserving ride quality and everyday drivability
• Driver-Selectable On-Demand Operation — Dash switch control allows precise engagement and disengagement of locking traction exactly when and where it is needed
• Net-Forged Internal Gears — Precision-forged gears are designed to mesh perfectly, providing improved strength and durability over standard cut gears
• Four-Pinion Gear Design — Available models feature a four-pinion configuration for smooth engagement and validated strength under demanding loads
• Extend Differential Service Life — Routine maintenance with genuine service kits prevents premature wear of critical electromagnetic and mechanical components
• Restore Factory Performance — Returns the ELocker to factory-specification engagement and disengagement behavior for consistent, dependable locking performance

Eaton ELocker Service Kits are the correct maintenance solution for the full range of ELocker electromagnetic locking differentials. Using genuine Eaton service components is the most reliable way to protect your investment and maintain the performance standards the ELocker system was engineered to deliver.
