Heavy Duty 3/4in Suspension Tube 18in

The ALLSTAR PERFORMANCE Heavy Duty 3/4in Suspension Tube 18in (ALL 57470) is a precision-engineered suspension component built for custom fabrication, race car assembly, and off-road vehicle builds. Constructed from steel with black paint finish, this 18-inch tube features a 1-inch outer diameter and 3/4-16 inch female thread, making it a versatile structural element for suspension geometry modifications and frame reinforcement work.

The tube's 1-inch OD provides excellent strength-to-weight characteristics for welded suspension assemblies, while the 3/4-16 female threads allow direct integration with standard suspension components and rod ends without additional adapter hardware. At 2.09 pounds, the compact 18-inch length serves as a control arm, tie rod, or strut tower brace application depending on your suspension layout. The black paint provides corrosion resistance during storage and initial assembly, though powder coating or additional surface treatment is recommended for long-term outdoor durability in salt-air or high-moisture environments.

This suspension tube is ideal for fabricators, race teams, and performance enthusiasts building custom double-wishbone suspensions, A-arm geometries, or independent rear suspension systems. Shops restoring vintage muscle cars, building competition off-road rigs, or designing formula-style open-wheel chassis rely on tubes like this to maintain precise suspension kinematics while keeping component weight minimal. The ALLSTAR PERFORMANCE brand is known throughout the fabrication community for producing standardized components that meet dimensional consistency and material quality expectations.

Whether you're replacing a worn suspension member, extending an existing assembly, or starting a custom suspension design from scratch, having properly dimensioned tubes with accurate threading ensures repeatable results and eliminates costly re-fabrication. The 18-inch dimension and female thread configuration make this tube compatible with most standard aftermarket suspension kits and rod-end hardware available through performance suppliers.
