Mazda RX-7 Subframe Cross Member for Sale

Replace the lost accuracy of the handling and the underbody rigidity of your Mazda RX 7 with a solid, factory style subframe cross member. Designed to suit structure and performance, this component is crucial to the chassis coordination of your RX-7 and suspension geometry, and a critical upgrade or replacement in old or rusted previous cross members.

Mazda RX-7 Subframe Cross Member

The cross member of the subframe in your Mazda RX-7 is an important structural part that holds most of the suspension parts, steering systems and the engine subassemblies. Key chassis points are joined and the forces exerted by the wheels and the drivetrain are balanced evenly throughout the frame mounted underneath the car. When a cross member becomes weak due to the corrosion, fatigue or impacts, the driving ability and safety can be hit hard.

  • Anti-corrosion treated for long service life
  • Compatible with OEM bushings, mounts, and fasteners
  • Designed for direct bolt-on installation—no modifications needed
  • CAD-modeled to fit RX-7 chassis with factory specifications
