Differential Eaton 912A686

Eaton differential / carrier. This is a build component selected by SPECIFICATION rather than by a single vehicle application: match the frame size, flange, wheel size and A/R to your build. If you are not certain what your build needs, ask a tech before ordering.

What it does

The differential lets the wheels turn at different speeds through a corner while still sending power to both. An open diff gives up the moment one tyre loses grip; a limited-slip or locker keeps both wheels driving, which is the difference between working and being stuck. A worn carrier also lets the gears walk out of mesh.

How to choose

• Match the compressor and turbine wheel sizes to your power target and drive style
• Match the turbine housing A/R and flange to the manifold and downpipe you are running
• Confirm the oil and coolant feed arrangement matches your engine
• Check the part number against the component you are replacing

Fixes

• one wheel spinning while the other does nothing
• a worn or cracked carrier
• chatter or banging on tight turns
• a build or a truck that has to work in the wet, mud or snow

What's included

• the differential or carrier at the spline count and ratio range stated
