Eaton’s New Electronic Locking Differential Reaches New Heights In Performance
SOUTHFIELD, MICH. – Diversified industrial manufacturer Eaton Corporation has developed a
new electronic locking differential, the Eaton ELockerTM, application for Jeep® products equipped
with the Dana 30 axles. With the simple press of a button, the new ELocker provides off-road
performance enthusiasts with superior traction and drivability.
With its four-pinion design, the new ELocker withstands the deep gearing, large tires and harsh offroad
terrain that would tax even the most robust original equipment component. The new Eaton
ELocker will be available for stock 27-spline axle or the high-performance 30-spline axle.
“We designed this selectable locker for the true Jeep enthusiast,“ said Jeff Romig, general
manager, Eaton Performance Products. “The unit is built to withstand the rigors of wheeling
through trails of mud and sand, and even climbing rock surfaces, yet when turned off it provides
the road manners people have come to expect from Eaton differentials.”
When extra traction is needed on loose or slippery terrain, drivers can simply flip a switch to lock
the axle containing the Eaton ELocker to deliver equal power to the front wheels. In the normal or
unlocked mode, the ELocker delivers the handling characteristics of an open differential. In the
locked mode, it offers additional traction for the most difficult terrain. The ELocker can even be
activated while the vehicle is in motion, provided both front wheels are turning at equal speed and
The Eaton ELocker uses electromagnets to push locking pins into a sturdy collar. The collar locks
the axle-side gear into the differential case, performing as a spool to deliver equal power to both
front wheels. This system is less complicated than an air-operated system and easier to install,
because it does not require an add-on air compressor.
