Open Diff Next To Eaton Elocker

The Dana 30 open differential (left) is nothing to write home about. Found in the front of many Jeep 4x4s, ours had 3.50 gears and puny axleshafts and would quickly send all the power to whichever wheel had the least traction. The solution is Eaton’s ELocker with Superior’s 4.10 gears (right). This selectable locker has a four-pinion open carrier but still locks into a spool for traction when needed.
