Aluminum Tunnel Kit - .040in Thick

The Aluminum Tunnel Kit - .040in Thick from CHASSIS ENGINEERING is a purpose-built solution designed for custom vehicle fabrication, restoration, and engine swaps. This kit is ideal for high-performance builds where factory tunnels are unavailable or incompatible with modern drivetrain configurations. It addresses critical structural and aesthetic needs in frame-up restorations and competition vehicle construction.

Manufactured from .040-inch aluminum, this tunnel kit balances strength with weight savings, making it a critical advantage for performance and vintage racing vehicles. The aluminum construction provides sufficient structural rigidity for driveline vibration isolation and chassis flex resistance while remaining lightweight compared to steel alternatives. This material also allows for straightforward modifications during fitment and resists corrosion in long-term storage or marine environments.

The pre-formed geometry of the tunnel kit eliminates guesswork in centerline alignment and driveshaft geometry, significantly reducing installation time and minimizing the risk of binding. Whether you're fitting a modern engine into a classic platform or building a street rod from the ground up, this precision-engineered tunnel kit ensures proper clearance and structural integrity from day one. It is an essential component for anyone looking to enhance their vehicle's performance and reliability.
