Suspension Tube 16in x 5/8in-18 THD

The Suspension Tube 16in x 5/8in-18 THD by WEHRS MACHINE is an essential component for builders and racers who demand precision in their suspension geometry and load-bearing applications. Manufactured by WEHRS MACHINE—a trusted name in high-performance suspension and fabrication—this 16-inch tube serves as a critical link in custom suspension systems, roll cages, and chassis reinforcement. Whether you're building a road-course competitor, drag racer, or street machine with custom geometry, this tube provides the rigid, predictable foundation that separates a safe, responsive setup from a compromised one.

The 5/8-inch outside diameter with 18 threads-per-inch (TPI) specification allows for secure, repeatable fastening in welded assemblies and allows builders to thread components directly into the tube without separate bungs or inserts. At 1.58 lbs and measuring 16 inches in length, this tube balances strength-to-weight efficiency—critical in performance applications where unsprung mass directly affects suspension compliance and responsiveness. The precise dimensional tolerances maintained by WEHRS MACHINE ensure that multiple tubes can be stacked, welded, or threaded with consistent geometry, eliminating the variation that plagues mass-produced alternatives and guarantees proper suspension alignment and component binding-free operation.

This suspension tube is ideal for fabricators, race teams, and dedicated enthusiasts building independent front or rear suspension systems, coilover mounts, or control arm assemblies where threaded interfaces are required. It works seamlessly in applications ranging from circle-track cars and autocross platforms to street rods and off-road buggies. Compatibility depends on your chassis design and suspension architecture; verify mounting points, load paths, and thread engagement depth before assembly to ensure optimal safety and performance margins.
