  • Increases oil capacity by 0.7 quart for higher thermal capacity
  • Half-inch external fins improve heat dissipation, lower differential fluid temperature, and increase impact resistance

  • External fins and internal scrapers work together to form an ultra-strong Cross-Bracing structure
  • Cast-in gussets for additional differential housing flange support and increased rigidity
