3/8 Aluminum Scalloped Tube - 8.5in.

The 3/8 Aluminum Scalloped Tube measures 8.5 inches in length and features a 3/8-24 inch female thread, making it a precision component for suspension and chassis applications requiring lightweight aluminum construction. The scalloped design reduces weight while maintaining structural integrity—a critical consideration in performance tuning where unsprung mass directly impacts ride quality and handling responsiveness. Black anodized and natural finish options provide corrosion resistance suited to both street and off-road environments.

At 0.17 lbs, this tube delivers minimal mass contribution to your build while the aluminum material offers superior strength-to-weight ratio compared to steel alternatives. The 3/8-inch diameter and 24 TPI threading are standard in precision suspension systems where thread pitch tolerance directly affects preload consistency and tuning repeatability. The anodized finish protects against oxidation and corrosion without adding measurable weight, essential for vehicles exposed to moisture, salt air, or extended storage periods. The scalloped profile is engineered to reduce rotational inertia in applications where smooth, predictable engagement matters.

This component suits chassis builders, suspension fabricators, and performance enthusiasts working on custom damper setups, preload adjusters, or modular suspension platforms. Its compact 8.5-inch length and lightweight profile make it ideal for space-constrained builds or weight-critical applications where every fraction of a pound influences performance. The 3/8-24 threading is common across aftermarket suspension brands, ensuring compatibility with standard adjuster sleeves, collars, and retention hardware used in modern coilover and adjustable spring platforms.

Aluminum suspension tubes like this are foundational to precision tuning—offering cost-effective weight reduction without sacrificing durability. Whether you're fine-tuning preload on an established platform or fabricating a custom chassis, the aluminum scalloped tube provides the structural foundation and lightweight advantage that serious builders demand from performance components.
