Take your rock crawling adventures to the next level with this HD Overdrive Machined Helical Diff Gear Set, designed to enhance performance where it matters most.

Master the Climbs: By increasing the rotational speed of the front wheels, this gear set gives you a powerful advantage on steep ascents, making tough climbs feel effortless.
Sharper Steering: Overdrive improves front-end grip, delivering tighter, more responsive steering to navigate technical trails with precision.
Higher Torque Capacity: Helical gears can handle greater torque loads, making them ideal for demanding climbs and heavy-duty crawling scenarios.
Quieter Performance: Helical gears engage gradually along their helical teeth, reducing noise and vibration compared to straight-cut gears.
Less Drivetrain Shock: The gradual engagement also minimizes sudden impacts, ensuring smoother power transfer and increased component longevity.
Rugged Durability: Dominate rugged landscapes with confidence! Machined from high-strength steel, this Diff Gear Set is built to withstand the toughest challenges.
Precision Fit: As an official HPI upgrade, this part is engineered to exact factory specs, ensuring a seamless bolt-in installation.
