3/4 Aluminum Scalloped Tube - 17.5in.

The 3/4 Aluminum Scalloped Tube - 17.5in. is a precision-engineered suspension component designed for high-performance racing and motorsports applications. Built by QUICKCAR RACING PRODUCTS, this aluminum tube delivers the lightweight strength critical for fabricating custom suspension linkages, control arms, and structural reinforcements in race cars and modified vehicles. If you're building a competition chassis or upgrading factory suspension geometry, this scalloped design reduces unsprung weight while maintaining rigidity where it counts.

Constructed from aluminum and finished in black anodized or natural coating, the 3/4 aluminum scalloped tube features a 3/4-16 female thread at both ends, allowing seamless integration with rod ends, spherical bearings, and standard suspension hardware. The scalloped profile—a series of cutouts along the tube's length—reduces overall weight to approximately 1.07 pounds while maintaining torsional rigidity, a critical trade-off in fabricated suspension work. At 17.5 inches long, this tube length suits mid-travel control arms, panhard bars, and track-width adjusters common in bracket racing, circle track, and street rod applications. The black anodized finish resists corrosion and provides a professional appearance; natural aluminum offers full weldability for custom fabrication without coating interference.

Fabricators, suspension shops, and serious DIY racers benefit most from this component when designing adjustable or custom-geometry suspension systems. The 3/4-16 female thread accepts industry-standard male rod ends and jam nuts, making it compatible with both OEM and aftermarket suspension kits. Installation requires welding expertise or a press-fit assembly with proper bearing hardware; ensure your fabricator checks thread engagement and applies appropriate preload to prevent slop. Whether you're building a tube frame chassis, correcting geometry on a modified drag car, or experimenting with suspension tuning, this scalloped aluminum tube delivers race-grade durability at a weight savings that directly impacts acceleration and handling response.
