Heavy-Duty Cast Aluminum Front Differential Cover for 2013-2025 RAM HD 9.25''-12-Bolt by Pacific Performance Engineering

Excessive heat can degrade differential fluid's protective qualities, causing accelerated gear and bearing wear. In limited-slip differentials, persistent high temperatures can break down clutch packs and friction modifiers, leading to reduced efficiency and compromised traction control. Cast from high-grade A356.0-T6 aluminum alloy, the PPE differential cover increases fluid capacity by .41 quart and features half-inch external cooling fins for enduring heat management and performance.

• High-Strength Aluminum Alloy: Premium A356.0-T6 heat-treated cast aluminum for durability and heat conduction
• Consistent Finish: Precision-cast using permanent steel molds for a smooth, uniform surface and accurate dimensions
• Increased Oil Capacity: Adds .41 quart for enhanced thermal capacity
• Enhanced Heat Dissipation: Half-inch external fins lower differential fluid temperature and boost impact resistance
• Reduced Heat and Aeration: Precision-placed internal windage scrapers minimize churning, heat, and fluid aeration
• Strengthened Structure: External fins and internal scrapers collaborate to form a robust Cross-Bracing system
• Added Support: Cast-in gussets reinforce differential housing flange and enhance rigidity
• Durable Service Plugs: 304 Stainless steel service plugs with high-temperature magnets and Viton O-rings
