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