Heavy Duty 5/8in Suspension Tube 12-1/2in

The ALLSTAR PERFORMANCE Heavy Duty 5/8in Suspension Tube 12-1/2in (ALL 57359) is a precision-engineered suspension component designed for custom chassis builds, street rods, and performance vehicle modifications. This 0.875-inch outer diameter tube measures 12.5 inches in length with 5/8-18 female threads on both ends, providing a robust connection point for suspension linkage, control arms, and tie-rod assemblies. The steel construction is finished with a durable black powder coat, offering corrosion resistance and a clean appearance in both show and street applications.

The 5/8-18 female thread specification is critical for suspension geometry tuning—this standard thread pitch allows precise length adjustment and repeatable alignment without slippage under load. The 0.875-inch OD provides adequate wall thickness for bending and torsional loads common in independent front suspension (IFS) and four-link rear suspension systems. Black powder coating protects against salt spray, moisture, and road chemicals, making this tube suitable for both weekend cruisers and vehicles exposed to harsh environments. At 1.24 pounds, the lightweight steel design minimizes unsprung weight while maintaining structural integrity under dynamic cornering and braking forces.

This suspension tube is ideal for fabricators, restoration shops, and enthusiasts building custom suspensions for hot rods, vintage trucks, and high-performance street vehicles. It serves as a control arm spacer, tie-rod extension, or adjustable linkage component in systems where OEM lengths do not accommodate custom geometry or ride height modifications. ALLSTAR PERFORMANCE is recognized in the automotive aftermarket for producing precision suspension and chassis components that meet the demands of both competition and street-driven vehicles. The 12.5-inch length and female thread design make this tube compatible with standard 5/8-18 rod ends and spherical bearings available from major suspension suppliers.
