Restore the integrity of your classic GM drivetrain with the Ratech 9.3-inch Pinion Seal. Specifically designed for the iconic GM 12-bolt rear end and 1963-1979 Chevy Corvettes, this seal is a critical component for any serious restoration or performance build. It effectively seals the pinion yoke to prevent oil loss and protect internal gears.
The GM 12-bolt is legendary for its strength, but it requires proper sealing to perform at its peak. This Ratech seal provides a tight, reliable barrier that prevents the common leaks associated with aged differential components. The combination of a high-temp rubber lip and a rigid steel outer ring ensures that the seal stays seated under varying thermal conditions and high torque loads. Installing a fresh seal is an inexpensive insurance policy against the costly damage caused by differential fluid starvation. Keep your classic Chevy or Corvette running smoothly with high-quality components from GGCRACING.
