The Eaton Corporation is well versed in the intricacies of engineering off-road capable-differentials, proven by the company's extensive line of locking and limited-slip diffs. Eaton's latest traction-adding differential, the ELocker, is a further advancement in the search for functional yet civilized traction. What makes the ELocker noteworthy is its electronic locking system, which allows the diff to function as an open differential when 100 percent traction isn't required. When total traction is called for, the push of a button electronically locks the ELocker, which locks the axles, delivering max traction.
Eaton manufactures the ELocker for Ford and GM axles, including '89-to-present GM 10-bolt axles with 30-spline shafts, '82-to-present GM 12-bolt axles with 33-spline shafts, '82-to-present GM 14-bolt axles with 33-spline shafts, '83-to-present 8.8 Ford axles with 31-spline shafts, and '83-to-present Ford 8.8 axles with 28-spline shafts. Here's an inside look at the Elocker's workings.
