3/8 Aluminum Scalloped Tube - 25.0in.

The QUICKCAR RACING PRODUCTS 3/8 Aluminum Scalloped Tube – 25.0in. (part #38-250) is a precision-engineered suspension component designed for high-performance racing and custom automotive builds. This aluminum tube features scalloped construction and 3/8-24 female threading, allowing seamless integration into adjustable suspension systems where fine-tuned ride height and geometry control are essential. Built from aluminum for weight savings without compromising structural integrity, it delivers the lightweight advantage critical in competitive racing environments.

At 25 inches in length with a compact cross-section (1.05 x 0.65 inches), this tube is engineered to fit restrictive packaging constraints while maintaining the thread pitch and mechanical advantage needed for reliable height adjustment under load. The scalloped profile reduces rotational weight while preserving bending stiffness—a critical consideration in double-A-arm and multi-link suspension designs where lateral forces are significant. Available in black anodized and natural finishes, the anodized variant offers corrosion resistance essential for vehicles exposed to salt environments or frequent washdowns.

This component is ideal for fabricators, suspension tuners, and bracket builders working on circle-track cars, street rods, and off-road vehicles where adjustable ride height or dynamic geometry adjustment improves handling balance. The 3/8-24 female thread accepts standard rod ends and heim joints, making it compatible with common adjustable suspension kits. Weighing just 0.52 pounds, the tube contributes minimally to unsprung mass—a key factor in suspension response and tire contact quality during cornering.
