Spindle Rocket XR1 Left

The PPM Racing Products Spindle Rocket XR1 Left is a precision-engineered front spindle assembly designed for trailer axles and marine launch applications. Built with steel construction and finished in durable black powder coat, this left-side spindle delivers reliable support for heavy-duty towing and boat recovery scenarios where structural integrity and corrosion resistance are critical to safe operation.

This spindle features a 6-degree geometry optimized for proper brake line routing and caliper alignment, paired with a 3.5-inch caliper mounting surface. The stock pin height configuration maintains compatibility with standard trailer frameworks, while the robust steel construction withstands the constant stress of launching, retrieving, and highway transport. Black powder coating provides a protective barrier against salt spray, moisture, and UV exposure—essential properties for waterfront equipment exposed to marine environments.

Boat owners, trailer mechanics, and marine recovery professionals rely on quality spindle assemblies to ensure safe braking performance and axle longevity. The Rocket XR1 left spindle addresses the specific wear patterns and corrosion challenges that occur in saltwater and freshwater launch environments. Whether you're replacing a worn spindle on a fishing boat trailer, upgrading a recovery winch frame, or building a custom launch system, this component provides the dimensional precision and material quality needed for years of reliable service.
