Aluminum Tubs 46in

The Competition Engineering Aluminum Tubs 46in wheel tubs (model C3005) are a purpose-built fabrication component for custom vehicle builds requiring controlled wheel well clearance and suspension geometry modifications. These aluminum wheel tubs are manufactured as a matched pair and provide the structural foundation necessary for low-slung chassis setups, custom suspension installations, and aggressive wheel offset configurations that demand internal wheel well extension.

Constructed from 0.032-inch thick aluminum with a beaded design that adds structural rigidity while maintaining the material's light weight, these tubs measure 46 inches in diameter with 23-inch height and 27.25-inch width, delivering substantial internal clearance for suspension components, brake lines, and custom control arm geometry. The beaded construction pattern is not merely aesthetic—it distributes stress across the panel surface, preventing flex and fatigue at high cornering loads or during dynamic driving. The natural aluminum finish provides a clean foundation for welding, powder coating, or custom painting to match any build aesthetic.

Fabricators, restoration shops, and serious drag racing or street rod enthusiasts rely on Competition Engineering wheel tubs when engineering vehicles with extremely low stance heights, custom trailing arm suspensions, or oversized wheel-and-tire combinations that exceed factory packaging. These components require professional welding installation and proper integration with existing frame structure, making them suitable for experienced builders and fabrication shops. The pair configuration ensures symmetrical geometry across both sides of the vehicle, critical for maintaining balance during acceleration, braking, and cornering.

Competition Engineering has established itself within the custom fabrication and hot rod communities as a supplier of quality metalworking components designed for serious performance modifications. These wheel tubs represent the kind of specialized, purpose-built hardware that separates engineered builds from bolt-on aftermarket upgrades.
