    RacingDiffs Large Oil Seal for Haldex Transfer Case — Ensure Optimal Performance

    The large oil seal between the Haldex transfer case and the rear differential is critical for drivetrain health. A leaking seal allows fluids to mix, reducing pump pressure and causing premature clutch wear in both the Haldex unit and the rear eLSD. Replace proactively to keep the system quiet, smooth, and reliable.

    Features
    • High-quality construction: Durable materials for a long-lasting seal.
    • Precise fitment: Designed to sit between the Haldex transfer case and rear differential.
    • Prevents fluid mixing: Keeps Haldex oil and rear eLSD oil separate to maintain pump pressure.
    • Easy installation: Direct replacement during drivetrain service.
    • Works with repair sets: Essential when servicing Haldex units or rear eLSD systems.
    Performance Benefits
    • Prevents premature clutch wear in Haldex and rear eLSD.
    • Maintains hydraulic pressure for consistent clutch operation.
    • Preserves drivetrain performance and longevity.
    • Reduces risk of faults caused by cross-contamination of oils.
