Description



What Does the 45% Dual Idler Gear Lift Offer?
  • Adds a second idler gear to the gearbox, improving the overall design.
  • Spreads the load over twice as many gear teeth, cutting stress in half.
  • Delivers more reliable torque transfer—especially critical when running large tires (40" or more).
  • Helps prevent broken axles, burnt belts, damaged differentials, and other drivetrain issues.
  • Offers stronger engine braking, reducing how often you need to use your brakes and extending brake life.

    Ideal for Larger Tires
  • 45% gear reduction is perfect for big tires and slow-speed torque.
  • Lower gear ratio restores lost torque without sacrificing durability.
  • Don’t need high speed? This gives you better power where it counts.

    Why Is This 6" Kit Better Than Competitors?
    Forged Gear Boxes
  • Strongest portal boxes available - much tougher than cast or billet aluminum.
  • Competitors use cast or billet; forging produces superior strength and reliability.

    Gear Box Venting
  • Optional venting plug lets you add a vent kit for better cooling.
  • Reduces wear on gaskets and seals by managing internal heat and pressure.

    Gasket & Seal Design
  • High-density Kevlar fiber gaskets - no extra sealant needed.
  • Gaskets resist oil, coolant, and distortion ("creep").
  • Dual oil seals on the spindle shaft for double protection.
  • Triple-seal input shaft includes a wiper seal for extra water and oil defense.

    Backing Plate
  • Built from 5/16" steel with bent flanges and welded gussets for unmatched strength.
  • Designed to fit all factory-spec control arms.

    13" Rotor
  • Precision-ground stainless steel rotors for top-tier brake performance.
  • Access holes make installation and removal easier.
  • Slotted design helps with heat dissipation and cooling.

    Gear Profile & Build Quality
  • Alloy steel gears go through a special heat treatment to boost strength.
  • CNC-machined for perfect fit and added durability.
  • Controlled lapping process ensures smooth, quiet operation.
