    Core Advantages (Exclusive to 456 Gear Ratio)

    1. Maximized Torque for Unmatched Recovery & Climbing Capability
      Compared with OEM 4.10/4.11: Torque output increases by approximately 11%, delivering stronger burst power for acceleration, climbing and off‑road recovery. It completely eliminates the “revving without forward motion” issue with 315/335 oversized tires, while ensuring smoother shifting and eliminating lugging.
      Compared with 430 (4.30): Higher low‑end torque for more confident rock crawling, mud recovery and heavy‑duty towing, ideal for extreme off‑roading.
      Compared with 488 (4.88): Lower RPM during highway cruising, better fuel economy and reduced noise, avoiding the excessive high RPM and fuel consumption spikes of 4.88 ratios. Perfect for mixed use of long‑distance overlanding and heavy off‑roading.
    2. High Strength & Durability, Impact & Fatigue Resistant
      Forged construction with precision heat treatment: Strengthened gear root for exceptional impact and fatigue resistance, capable of handling extreme conditions including rock bottoming, steep slope recovery and heavy towing.
      Abrasive coating + gear lapping process: High‑precision tooth surface with superior wear resistance, reducing meshing impact and extending service life (officially rated at 6–7 times the lifespan of standard gears).
      Matched production: Ring gear and pinion gear are lapped as a 1:1 matched set, ensuring precise meshing clearance after installation to minimize abnormal noise and wear.
    3. Quiet Design & Installation Support for Rattle‑Free Performance
      Upgraded optimized tooth profile + precision lapping: Smoother gear meshing, reducing drivetrain noise by 3–5dB compared with conventional gear sets, balancing off‑road performance and on‑highway comfort.
      Supplied with installation standards + one‑on‑one technical support: Resolves noise, overheating and gear chipping caused by improper installation, ensuring quiet and reliable performance right after fitting.
    4. Vehicle‑Specific, Non‑Destructive Fitment for Mainstream Rugged Models
      Key Fitment: Tank 300/400 (Gasoline/Diesel), Ford Ranger, BAIC BJ40 Series, 212 T01, Jeep Wrangler JL/JK, Isuzu D‑MAX, Jeep Gladiator and more.
      OEM mounting points + factory specifications: Direct replacement of the original gear set with no cutting or drilling required. Compatible with OEM differential housings and bearings, with no interference to the suspension, drive shaft or axles after installation.
