Cusco A Lower Arm Bar Type I Chassis Brace Air Suspension Helper Spring Kit

The Cusco Lower Arm Bar Type I is a performance chassis brace (also called a lower control arm brace or lower arm bar). It connects the left and right front lower control arm mounting points. This reduces body and subframe flex under hard cornering, acceleration and braking. The result is sharper steering response, better handling feel and more consistent traction.

Key Features:

• 2-point Type I design: bridges the lower arm mounting points to stiffen the structure where the suspension attaches to the chassis.
• Lightweight tubular aluminum construction: adds rigidity without adding much weight.
• Corrosion-resistant coating: protects against road salt and the elements.
• Bolt-on installation: installs with common hand tools and needs no welding or permanent modification.
• Vehicle-specific engineering: each Cusco brace is designed around the trouble areas of the chassis it is made for.
• Street and track use: suits daily-driven performance cars and track builds.

Cusco is a Japanese motorsport parts manufacturer known for chassis bracing, suspension and drivetrain components. The Type I lower arm bar is a simple way to improve chassis rigidity and driver feedback.
