Heavy Duty 5/8in Suspension Tube 18in

The ALLSTAR PERFORMANCE Heavy Duty 5/8in Suspension Tube 18in (ALL 57370) is a precision-engineered suspension component designed for custom chassis builds, vintage hot rods, and modern performance vehicles requiring rigid frame reinforcement. This suspension tube is an essential structural element for independent suspension systems, A-arm assemblies, and custom control arm fabrication.

Manufactured from heavy-duty steel with a 5/8-inch outside diameter, this suspension tube delivers the structural integrity necessary to handle cornering loads, acceleration forces, and impact stress without deflection or permanent deformation. The precise 18-inch dimension allows for accurate center-to-center measurements when welding ball joints, rod ends, or clevis mounts, which is critical for maintaining suspension geometry and ensuring predictable handling characteristics.

This component is ideal for fabricators, suspension shops, and serious enthusiasts building custom control arms or frame bracing systems. Its versatility across multiple vehicle platforms makes it a go-to choice for builders who need reliable, repeatable geometry when designing or modifying suspension kinematics.
