Cusco 666 265 L D1 Chromoly Roll Cage 7-Point 5-Passenger Through Dash

The Cusco 666 265 L is a D1-series chromoly roll cage engineered in a 7-point, 5-passenger, through-dash along-roof configuration. Built from 40mm diameter chromoly steel tubing with a wall thickness of 1.6mm, this cage delivers exceptional structural rigidity while weighing approximately 33% less than comparable mild steel roll cages. The result is a motorsport-grade safety structure that adds meaningful chassis stiffness without unnecessary weight penalty.

Developed from direct feedback from professional race teams and rally engineers, Cusco's D1 roll cage line reflects decades of competition experience. Each application is purpose-built and oriented to the most structurally relevant mounting points in the chassis for maximum effectiveness. The cage features high-strength, ultra-lightweight connection joints and is finished in Cusco's signature powder-coated metallic blue.
