Radius Rod Insert Top Mnt - Single Stack 15in

The Radius Rod Insert Top Mount Single Stack 15-inch from HEPFNER RACING PRODUCTS is a precision marine suspension component engineered for high-performance watercraft and go-fast boats. This radius rod insert delivers the rigid geometry and load-bearing capacity critical to maintaining predictable handling dynamics at speed, whether you're running coastal waters or offshore. At 15 inches in length with a single-stack configuration, this insert is optimized for medium-duty applications where suspension compliance must be carefully balanced against structural integrity.

Weighing 1.3 pounds and measuring 4 x 3 x 13 inches, the Radius Rod Insert Top Mount is compact enough for tight engine compartments while maintaining the wall thickness and cross-sectional properties necessary to handle repeated stress cycles. The top-mount configuration positions the insert for direct mounting to the transom structure or engine framework, reducing installation complexity and minimizing potential load paths that could introduce unwanted flex. Single-stack design simplifies geometry compared to dual-stack alternatives, making this insert ideal for boats with space constraints or builders seeking straightforward alignment procedures.

Serious performance boaters and weekend fishermen alike benefit from the engineering focus HEPFNER RACING PRODUCTS brings to radius rod technology. Whether you're upgrading a stepped hull design, repairing a worn suspension system, or building a custom high-speed platform, this component addresses the specific geometry and load requirements that define modern marine powerboat handling. Proper radius rod inserts prevent excessive transom deflection under acceleration and cornering loads—a critical factor in maintaining prop bite and avoiding porpoising at planning speeds.
