5/8 Aluminum Scalloped Tube - 49in.

The 5/8 Aluminum Scalloped Tube – 49in. (QRP62-490) is a precision suspension component engineered for custom vehicle builders and dedicated motorsports enthusiasts who demand lightweight strength without compromise. Manufactured by QUICKCAR RACING PRODUCTS, this 49-inch aluminum tube is purpose-built for fabricating adjustable suspension links, chassis bracing, and control arm assemblies on drag cars, street rods, and performance street vehicles. The scalloped design reduces weight while maintaining structural integrity, making it an ideal choice for builders seeking to optimize weight distribution and improve handling dynamics on race-tuned or heavily modified platforms.

Constructed from high-grade aluminum and finished in black anodized or natural coating, this tube features a 1.5-inch square profile with 5/8-18 female threads on both ends, enabling quick connection to rod ends, clevis mounts, and adjuster hardware without additional machining. The scalloped geometry—strategically lightened cutouts along the tube's length—removes unnecessary material while preserving bending and torsional rigidity, resulting in a robust yet lightweight assembly that weighs just 2.6 lbs. At 49 inches long, the tube suits mid-length suspension geometry on most custom builds, and the female thread design allows for precision length adjustment via male-threaded rod ends or turnbuckle assemblies commonly used in adjustable suspension systems.

Professional fabricators, fabrication shops, and DIY chassis builders will find this aluminum scalloped tube essential for constructing upper or lower A-arms, tie rods, and diagonal braces on independent or traditional suspension setups. The 5/8-18 female threading accommodates standard rod ends and adjusters used across drag racing, circle-track, and street performance communities, ensuring compatibility with off-the-shelf suspension hardware. Installation requires basic welding or bolting to frame and control arm pivot points; the anodized finish provides corrosion resistance in harsh environments, while the natural finish option suits painters who prefer custom coating. Verify thread pitch compatibility with your chosen rod ends and confirm overall geometry against your suspension design before ordering.
