5/8 Aluminum Radius Rod 18.5in Polished

The Ti22 PERFORMANCE 5/8 Aluminum Radius Rod 18.5in Polished (SKU TIP2510-185) is a precision suspension tube engineered for high-performance marine and off-road applications requiring dependable rod geometry and corrosion resistance. This 18.5-inch aluminum radius rod features a 1.125-inch outer diameter with 5/8-18 female threads on both ends, delivering the structural integrity and repeatable geometry critical to suspension systems operating in saltwater and harsh environments.

Constructed from aluminum and finished in a polished surface, this suspension rod resists oxidation and corrosion far better than steel alternatives—a crucial advantage in marine applications where salt spray accelerates degradation. The 1.125-inch OD provides optimal stiffness-to-weight balance for suspension linkage, while the 5/8-18 thread specification ensures secure connection to clevis joints, rod ends, and adjustable mounts. Weighing just 0.66 pounds, it maintains minimal unsprung mass while delivering the precision geometry required for consistent handling and response. At 18.5 inches in length, this rod accommodates mid-travel to full-compression suspension designs in performance boats, jet skis, and offshore racing craft.

This radius rod suits high-performance boaters and marine mechanics building or rebuilding suspension systems where corrosion prevention and dimensional accuracy are non-negotiable. Offshore anglers running center console or tournament fishing vessels benefit from the durability of aluminum in saltwater exposure, while performance enthusiasts tuning jet ski or personal watercraft suspension systems rely on Ti22's reputation for precision engineering and consistent tolerances that integrate seamlessly with existing linkage assemblies.

Ti22 PERFORMANCE specializes in suspension geometry and performance tuning components trusted across marine racing, powerboat, and high-performance recreational boating sectors. The polished finish not only resists corrosion but also simplifies visual inspection of the rod for stress cracks or fatigue—critical for maintenance on systems operating under dynamic loads. Whether replacing a worn radius rod, upgrading suspension geometry, or building a custom linkage from components, this aluminum rod delivers the accuracy and environmental resistance demanded by serious boaters.
