Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Differential Repair & Maintenance: The Differential Repair Kit includes critical components like the OEM-certified 41331-1440 differential assembly, 16T/29T side gears, and a 32x215 spider gear. These parts ensure precise torque distribution and smooth operation in truck drivetrains.
  • Gear Compatibility: Designed for Hino trucks, the kit features gears with specific tooth counts (e.g., 16T/29T) and diameters (e.g., 82mm and 32mm) to restore differential functionality in high-stress driving conditions.

Key features

  • 1. Advanced Material Technology

    • With a 20crmntih alloy steel construction, this differential repair kit ensures exceptional durability and corrosion resistance. The material’s high strength and wear resistance outperform standard steel components, extending service life in harsh industrial environments.

  • 2. Precision OEM-Engineered Design

    • Designed as an OEM replacement (41331-1440), this kit guarantees seamless compatibility with Hino truck models. Its precise fit reduces installation time and eliminates the need for custom adjustments compared to generic aftermarket parts.

  • 3. Optimized Gear Performance

    • Equipped with 16T/29T gear ratios and a 32x215 spider gear, this assembly delivers balanced torque distribution and smooth power transmission. The design improves efficiency by ~15% over non-optimized gear systems*.

  • 4. Commercial-Grade Reliability

    • Built for heavy-duty commercial use, the kit supports continuous operation under high loads. Its compact size and robust construction make it ideal for rugged truck applications, unlike lighter-duty alternatives.

  • 5. Certified OEM Compliance

    • Manufactured to Hino’s original specifications, this kit meets strict quality and safety standards. It ensures seamless integration with transmission systems, avoiding compatibility issues common with non-OEM parts.

Supplier's note

  1. Technical Breakthroughs:

    • 20crmntih Alloy Steel: Triple the fatigue resistance of standard SAE 1045 steel, enabling longer service life in harsh environments.
    • Precision Gear Teeth Design: ±0.01mm tolerance ensures minimal backlash and noise reduction.
    • Modular Components: Interchangeable spider and side gears simplify repairs without full assembly replacement.

  2. Optimal Version Selection:

    • Base Model: Ideal for routine maintenance in urban or light-commercial use.
    • Advanced Model: Recommended for frequent off-road or heavy-load applications (e.g., logging, mining).
    • Pro Model: Designed for extreme-duty vehicles (e.g., long-haul trucks) requiring resistance to corrosive fluids and extreme temperatures. With its chemical resistance rating exceeding industry standards, the Pro Model safely handles exposure to diesel additives and high-temperature braking systems. Pair its 6,500 Nm load capacity with the 20crmntih material’s high tensile strength to prevent catastrophic failure in critical operations.
