    • Detailed description
    IKNA 430 Gear Ratio (4.30:1) is a competition-grade final drive gear set developed by IKNA exclusively for rugged Off-road vehicles and Pickups, including Tank 300/400, Ford Ranger, BAIC BJ40, 212 T01 and other models.
    It resolves key pain points caused by oversized tires: sluggish power delivery, weak climbing performance, erratic shifting logic and elevated fuel consumption. Built for high strength, precision, quiet operation and durability, it comes with a 100-day breakage warranty and is one of the most popular ratio upgrades for off-road enthusiasts running larger tires.

    Core Advantages (Exclusive to 430 Ratio)

    Material: Steel

    1. Golden Balance of Power & Fuel Efficiency

    (4.30 vs. OEM / 4.56 / 4.88)

    • Compared with OEM 4.10/4.11: Torque output increases by approximately 5%, delivering quicker acceleration and stronger climbing performance. Shifting becomes smoother with 285/70R17 and larger tires, eliminating the “revving without forward motion” issue.

    • Compared with 4.56/4.88: Lower RPM during highway cruising, improved fuel economy and reduced noise. Ideal for long-distance overlanding combined with daily commuting, avoiding the excessive high RPM and fuel consumption spikes common with 4.56/4.88 ratios.

    Ideal Use Case: The top choice for vehicles equipped with 285–315 oversized tires, mixed on‑road and off‑road use, and enthusiasts unwilling to compromise highway fuel economy.

    2. High Strength & Durability, Impact & Fatigue Resistant

    • Forged construction with precision heat treatment delivers high gear root strength, enabling resistance to impact and fatigue for rock crawling, steep-slope recovery and heavy-duty towing.

    • Gear lapping and abrasive coating ensure high tooth surface precision and superior wear resistance, reducing meshing impact and extending service life (officially rated at 6–7 times the lifespan of standard gears).

    • Paired production: Ring gear and pinion gear are lapped as a matched set, ensuring precise meshing clearance after installation to minimize noise and wear.

    3. Quiet Design & Installation Support, Eliminating Modification Noise

    • Optimized tooth profile and precision lapping enable smoother meshing and lower drivetrain noise, making it quieter than conventional gear sets.

    • Includes installation standards and one-on-one technical support to resolve noise, overheating and gear chipping caused by improper fitting, guaranteeing quiet, reliable performance once installed.

    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 and more.
    OEM mounting points and factory specifications allow direct replacement of the original gear set with no cutting or drilling required. It matches the OEM differential housing and bearings, with no interference to the suspension, drive shaft or axles after installation.
