Suspension Tube 5.5in x 5/8-18 THD

The WEHRS MACHINE Suspension Tube 5.5in x 5/8-18 THD is a precision suspension component designed for custom vehicle builds and high-performance chassis fabrication. Built by WEHRS MACHINE—a trusted manufacturer in the fabrication and suspension modification market—this tube serves as a critical structural element in custom suspension geometry setups. Whether you're engineering a tube frame drag car, road course rig, or street-driven hotrod, this suspension tube provides the dimensional accuracy and thread consistency required for repeatable, reliable builds.

This suspension tube measures 5.5 inches in length and features a 5/8-18 coarse threaded specification, which refers to a 5/8-inch diameter with 18 threads per inch—a standard coarse-pitch threading widely used in suspension linkages, control arm pivots, and A-arm fabrication. The 5/8-18 thread pitch ensures secure fastening under dynamic load conditions while maintaining compatibility with common suspension hardware and rod ends. The precision-machined construction guarantees concentric thread runout and dimensional consistency across multiple builds, critical when tuning suspension geometry to exacting specifications.

Fabricators, chassis builders, and suspension engineers rely on WEHRS MACHINE components for drag racing, circle track, road racing, and custom suspension applications. At just 0.52 lbs, the tube's compact weight makes it ideal for weight-sensitive applications where every fraction of a pound impacts handling balance and acceleration. This suspension tube is designed to meet the needs of serious automotive enthusiasts looking to enhance their vehicle's performance.
