Strengthen Your Classic A-Body Chassis

The BMR Suspension Rear Shock Tower Brace (STB412) is the perfect solution for reinforcing the rear chassis of your 1964-1972 GM A-Body. These classic vehicles are prone to chassis flex, which can negatively impact handling and performance, even with mild power levels. This two-point brace connects the rear upper shock mounts, adding the necessary strength and support to keep your suspension geometry stable.

Engineered for Classic Performance

  • Superior Construction: Made from lightweight DOM steel tubing and laser-cut 3/16-inch steel plate for maximum strength.
  • Chassis Reinforcement: Ties the rear shock towers together to significantly reduce frame flex.
  • Improved Handling: Provides a more predictable and responsive rear suspension feel.
  • Black Hammertone Finish: Durable, professional-grade finish that blends perfectly with classic undercarriages.
  • Complete Kit: Includes all necessary Grade 8 hardware for a straightforward installation.

Whether you are restoring a Chevelle, GTO, or Cutlass, the BMR Rear Shock Tower Brace is an essential upgrade for any performance-minded build. It ensures that your rear suspension is fully supported, allowing for better traction and more precise cornering. Don't let chassis flex hold your classic muscle car back from its true potential. Trust GGCRACING to provide the high-quality suspension components you need for your next project.
