3/8 Aluminum Scalloped Tube - 14.5in.

The 3/8 Aluminum Scalloped Tube – 14.5in. (SKU: QRP38-145) is a precision suspension component engineered for custom vehicle builds, lowering kits, and adjustable suspension systems. Fabricated from lightweight aluminum and finished in black anodized or natural coating, this tube excels in applications where weight savings, corrosion resistance, and adjustability are critical. Whether you're engineering a coilover system, designing a custom air suspension, or building a race-oriented independent suspension, this scalloped aluminum tube delivers the geometry flexibility and durability demanded by serious automotive modifiers and fabricators.

Machined from 3/8-inch diameter aluminum stock with an integrated female thread (3/8-24in.), this 14.5-inch tube features precision scalloping—strategically cut recesses that reduce overall weight while maintaining structural rigidity and allowing rod-end bearings or spherical joints to achieve full range of motion without binding. The black anodized finish provides superior corrosion protection and a professional appearance, while the natural aluminum option is ideal for builders who prefer raw aesthetics or plan custom finishing. At only 0.29 lbs per unit, aluminum construction delivers meaningful weight reduction across multi-tube suspension assemblies without compromising strength or fatigue resistance.

This component is ideal for fabricators building custom A-arms, control arms, or adjustable tie-rod assemblies on street rods, drift platforms, and competition vehicles. The 3/8-24 female thread accommodates standard tie-rod ends, spherical bearings, and rod-end hardware, making it compatible with both OEM-style and performance-aftermarket fasteners. Installation requires basic threading and welding skills; ensure proper alignment and torque specifications when connecting to frame or suspension pickup points. Verify suspension geometry calculations and clearance before final assembly to guarantee full articulation and prevent binding during compression or extension cycles.
