  • Grade B specification for specific compression requirements
  • Designed, engineered, and tested to GM's rigorous standards
  • Seals combustion chambers, coolant passages, and oil galleries
  • Direct replacement for factory-installed gasket

ACDelco GM Original Equipment parts are manufactured to meet or exceed strict General Motors quality requirements, ensuring proper fit, performance, and service life.
