HRSATF891E - 91t 48p Steel Spur Gear Arrma 1:10 4x4

Steel spur gear with 91 teeth at 48 pitch engineered to replace the stock nylon spur gear in 1/8 scale Arrma 4x4 RC vehicles for increased durability and drivetrain strength. Precision CNC machined hardened steel resists wear and deformation under high torque loads compared with plastic gears. Designed to mesh cleanly with compatible 48 pitch pinion gears for smooth power transfer and consistent gear engagement. Direct replacement that fits in Arrma 4x4 transmissions without modification. Ideal for bashing and racing applications where steel gear resilience improves drivetrain longevity.

• Hardened steel construction for superior strength and wear resistance.
• 91T and 48 pitch tooth count for Arrma 4x4 drivetrain compatibility.
• CNC machined for precise tooth form and reliable mesh.
• Direct replacement for stock spur gear using factory hardware.
• Maintains consistent engagement under high torque demands.
• Improves drivetrain reliability in off-road and high-speed use.
• Reduces risk of stripped teeth compared with plastic gears.
