3/4 Aluminum Scalloped Tube - 34in.

The QUICKCAR RACING PRODUCTS 3/4 Aluminum Scalloped Tube – 34in. is a precision-engineered suspension component designed for high-performance automotive and motorsports applications where weight savings and structural integrity are equally critical. Built from aluminum and featuring a scalloped design, this 34-inch tube delivers the strength required for suspension geometry adjustments while maintaining the lightweight profile that serious racers and suspension shops demand.

Measuring 1.5 x 1.5 inches in cross-section with a 3/4-16 inch female thread specification, this suspension tube integrates seamlessly into adjustable suspension systems where axle tubes, control arm extensions, and radius rod assemblies require repeatable length and thread compatibility. The scalloped profile reduces material without sacrificing torsional rigidity—a critical design feature in chassis setups where tube flex can compromise handling consistency. Available in black anodized and natural finishes, the anodized variant provides corrosion resistance essential for vehicles exposed to salt spray or moisture-heavy environments, while the natural finish allows straightforward finishing at the fabricator's discretion. At 2.2 lbs, this component contributes minimally to unsprung weight while maintaining the dimensional precision necessary for alignment reproducibility across multiple setups.

QUICKCAR Racing Products tubes are standard in fabrication shops building bracket-style suspension systems, off-road chassis, drag racing frames, and road-course geometries where custom axle lengths or control arm extensions are required. This particular 34-inch length suits mid-wheelbase platforms and dual-purpose setups where longer radius rods or adjustable trailing arms demand extended reach without requiring full-length chassis tubing. The female thread design enables bolt-on connections to adjuster sleeves, jam nuts, and spherical bearing rod ends—components typically sourced separately but essential to the complete suspension assembly.

Whether building a street rod, circle-track car, or off-road buggy, the scalloped aluminum tube remains a cost-effective solution to suspension geometry challenges. Quality fabrication shops stock multiple lengths; this 34-inch version serves as a versatile intermediate size for most rear-end and front-geometry applications where shorter tubes prove inadequate and full-frame lengths introduce unnecessary weight or complexity.
