Eaton ELocker Service Kit - Electromagnetic Locking Differential Maintenance

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

About the Eaton ELocker System:

The Eaton ELocker is an electronic, selectable locking differential built for drivers who need dependable traction at the push of a button. Under normal driving conditions, the ELocker operates as a conventional open differential, preserving on-road handling, tire wear, and fuel efficiency. When activated via a dash-mounted switch, the electromagnetic mechanism fully locks, capturing 100% of available torque and distributing it equally to both driven wheels. A second press of the switch instantly returns the unit to open differential operation. Internal gears are net-forged for the strength and durability demanded by 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
