Description

The Dynatrac DA60-1X3131-H is a spindle/needle bearing, specifically a free-spin service part designed for heavy-duty applications. It is an integral component of Dynatrac Free-Spin Kits, which replace the factory unit bearings with a traditional spindle, hub, and bearing design, improving durability and reducing rolling resistance. This part is typically used in pairs and is compatible with various Dodge and Ford truck models when used with the appropriate Dynatrac Free-Spin Kit.
