Cusco 380 476 A Type I Rear Lower Arm Bar 2-Point Aluminum Under Brace

The Cusco 380 476 A Type I Rear Lower Arm Bar is a performance chassis reinforcement brace engineered to reduce body flex and sharpen chassis dynamics. Constructed from tubular high-tension aluminum and finished in Cusco's signature blue anti-corrosion coating, this bar delivers a meaningful improvement in rigidity while keeping weight to an absolute minimum.

Key Features:

• Tubular aluminum construction — high-tension, lightweight design reduces unsprung weight without sacrificing structural integrity
• 2-point lower arm connection — links the rear lower arm mounting points on both sides to resist chassis flex under load
• Anti-corrosive blue anodized finish — protects against moisture, road grime, and the elements for long-lasting durability
• Improved steering response and traction — reduced chassis flex translates directly to more precise steering feel and better corner exit grip
• Complete hardware included — all mounting hardware is provided for a straightforward installation
• Hand-tool installation — bolts on using standard hand tools with no cutting or modifications required

The Cusco 380 476 A is a Type I (Ver. 1) design, meaning it utilizes a clean two-point mounting layout that braces the rear subframe lower arm positions. This is an ideal entry-level chassis brace for drivers looking to tighten up chassis response on the street or track without major modifications. Cusco part number cross-reference: 075-159-107.
