Power Train Components 4370N Transfer Case Output Shaft Seal Gaskets & Seals

The Power Train Components 4370N is a high-quality transfer case output shaft seal designed to prevent fluid leaks and keep contaminants out of critical drivetrain components. This precision-engineered seal features a spring-loaded, multi-lip design that provides superior sealing performance and long-lasting durability.

Key Features:

• Polyacrylate rubber construction offers excellent resistance to heat, oil, and extreme pressure lubricants
• Spring-loaded multi-lip design ensures optimal contact pressure and superior sealing efficiency
• Counter-clockwise spiral lip design directs fluid back into the transfer case to reduce leak risk
• Reinforced outer case helps prevent installation damage and enhances durability
• Integrated dust boot lip protects against harmful contaminants, rust, and corrosion
• Ribbed rubber inner diameter seals minor bore imperfections and promotes positive seating
• Vent holes allow lubricants to flow freely around the seal lip, cooling components and removing heat buildup
• Temperature range: -20°F to 300°F (-29°C to 149°C)

Specifications:

• Inside Diameter: 1.503 inches (38.18mm)
• Outside Diameter: 2.383 inches (60.53mm)
