5/16 Aluminum Scalloped Tube - 8in.

The 5/16 Aluminum Scalloped Tube – 8in. from QUICKCAR RACING PRODUCTS is a precision-engineered suspension component designed for fabricators, drag racers, and serious enthusiasts building custom chassis or adjustable suspension systems. Scalloped tubes are essential for quick-adjustable suspension builds where riders or drivers need to fine-tune geometry on the fly—whether you're tuning a drag car's launch angle, adjusting a bracket racer's weight transfer, or dialing in a custom street rod's stance. This aluminum construction keeps weight minimal without sacrificing strength, making it the go-to choice for competitors who count every pound.

Built from aluminum with a black anodized or natural finish, this 8-inch tube features a 5/16-24 female thread, allowing secure connection to matching male threads on control arms, links, or adjustment brackets. The scalloped design—essentially a grooved or fluted profile along the tube's length—enables quick visual alignment and faster threading, reducing assembly time during pit stops or setup changes. At just 0.16 lbs, the lightweight profile minimizes unsprung weight while maintaining the rigidity required for suspension loads. The anodized finish provides corrosion resistance and durability in harsh racing environments, while the natural finish option offers flexibility for custom finishing or welding applications.

This suspension tube is ideal for door-slammer drag racers, bracket racers, and custom fabricators who demand repeatable, adjustable geometry. It pairs seamlessly with QUICKCAR suspension kits and universal racing setups where quick-change components reduce downtime between runs. Installation requires basic threading knowledge and standard wrenches; ensure proper thread engagement and torque to avoid slipping under load. The 8-inch length suits most control arm applications, but always verify mounting points and thread compatibility before assembly. Whether you're competing at the strip or building a bespoke hot rod, this scalloped tube delivers the adjustability and reliability that serious racers depend on.
