Eaton Differential Carrier SoftLocker (MPN: 187SL13A)

Enhance drive feel with automatic locking differential technology.

The Eaton Differential Carrier SoftLocker is designed for the Ford 9 Inch axle, featuring an automatic locking mechanism that improves vehicle handling and performance. This innovative differential utilizes a spring-generated preload between the side gears to create rotational resistance, which dampens the re-engagement action of the Detroit Locker. As a result, drivers experience a smoother drive feel, particularly on highways, without affecting the actual internal lash of the differential.

Constructed from durable steel, the SoftLocker is engineered for 28 spline applications with a gear ratio of 3.25 and higher. The internal Belleville style springs and wear disks enhance the functionality of the differential, although they are not essential for its operation. This product is identified by the inclusion of 'SL' in the model number, ensuring compatibility and performance for those seeking reliable differential solutions.

With its robust design and advanced features, the Eaton SoftLocker is a valuable addition for those looking to optimize their vehicle's differential performance. It provides a balance of strength and functionality, making it suitable for various driving conditions.
