3/8 Aluminum Scalloped Tube - 17in.

The 3/8 Aluminum Scalloped Tube - 17in. by QUICKCAR RACING PRODUCTS is a precision-engineered suspension component designed for high-performance race cars and modified street vehicles where weight savings and precise geometry are critical. Built from lightweight aluminum with black anodized and natural finish options, this scalloped tube serves as a suspension link or control arm component that reduces unsprung mass while maintaining the structural integrity needed for cornering loads and suspension articulation. Whether you're building a dedicated track machine or upgrading a street rod, this 17-inch tube delivers the compact sizing and thread geometry necessary for modern suspension tuning.

The scalloped design lightens the tube without sacrificing bending strength, a critical advantage in racing where every tenth of a pound reduces rotational inertia and improves acceleration response. The 3/8-inch diameter with 3/8-24 female threads on each end allows direct connection to rod ends, spherical bearings, or adjustable link hardware commonly used in independent suspension systems and chassis fabrication. At just 0.34 lbs, the aluminum construction provides an excellent strength-to-weight ratio compared to steel alternatives, while anodized and natural finishes resist corrosion and wear in high-vibration environments. The 17-inch length is ideal for intermediate suspension travel ranges, fitting A-arm assemblies, panhard bars, or track-width adjusters on compact platforms.

Mechanics and fabricators choose this suspension tube for cars requiring adjustable suspension geometry, roll center correction, or custom-length control arms where off-the-shelf parts don't fit the application. It pairs seamlessly with QUICKCAR's ecosystem of rod ends, spherical bearings, and adjustable link hardware, making it a go-to choice for autocross builds, bracket racing platforms, and street cars with modified chassis. Installation requires basic thread-matching verification with your chosen rod end or bearing hardware; ensure 3/8-24 compatibility before assembly. This tube is best suited for builders who understand suspension kinematics and need repeatable, lightweight geometry adjustments without the cost or lead time of custom-fabricated components.
