Eaton 26663-00S ELocker Stator/Armature Kit for Dana 30/35 ELocker Axles

Vehicle Fitment

• Various vehicles equipped with Eaton ELocker in Dana 30, Dana Super 30, Dana 35, Dana Super 35 axles (service type numbers 19817-010, 19818-010, 19819-010, 19821-010, 19822-010)

Fitment Notes

• This is a stator/armature service kit for ELocker differentials; it only fits those ELocker units listed above, not open or other locker/differential types. 
• Drivetrain: solid axle 4-wheel drive (4WD) or rear drive as applicable; respects front or rear installation depending on vehicle. 
• Fitment confirmed for these ELocker models through the latest published Eaton Performance Application Guide; 2025 model explicit listings not found - 2025 unconfirmed.
• Requires matching wiring, solenoid control, and appropriate mounting for the stator/armature to function correctly. 

Features

• Genuine Eaton stator/armature kit designed for ELocker electromagnetic locking mechanism.
• Includes stator assembly, magnetic armature, retaining bracket for proper locking and unlocking operation. 
• Allows restoring or maintaining the lock engagement performance when magnetic parts are worn or damaged. 
• High-quality OEM Eaton components to preserve tolerances, fit, and durability. 
• Designed for ease of installation when servicing ELocker assemblies - service kit format for internal locking mechanism. 
• Helps eliminate issues such as inconsistent lock, dragging or failure to lock under load. 
• Kit is built to OEM spec for magnetic coupling and mechanical cohesion. 
• Compatibility with multiple Dana 30/35 ELocker models to reduce SKU complexity for service techs.

Product Description

The Eaton 26663-00S is an OEM service kit for the stator/armature portion of the Eaton ELocker electromagnetic locking differential. It is specifically designed for Dana 30, Dana Super 30, Dana 35, and Dana Super 35 ELocker units (service types 19817-010, 19818-010, 19819-010, 19821-010, 19822-010). Over time, components like the stator core and armature in the ELocker can degrade, suffer magnetic wear, or become misaligned, resulting in weak or inconsistent lock engagement or failure to lock when required.

This kit includes all the internal magnetic components necessary to refurbish the locking mechanism (stator, armature, and bracket). Installation requires disassembling the ELocker's locking stator housing, removing the old worn magnetic parts, fitting the new stator core and armature, and re-installing with correct alignment and retention bracket. Because this is a service kit to restore factory lock performance, it's not a complete differential unit. Fitment through the last published Eaton Performance application guides is confirmed for those Dana 30/35 ELocker models; model year 2025 explicit inclusion is not documented. Always verify your differential's service type casting (19817-010, etc.) before ordering.
