The Steel Helical Differential Ring and Pinion Gear for Arrma Grom is a precision-machined upgrade featuring helical spiral-cut gears, which provide greater strength and smoother operation than stock bevel gears. Made from high-carbon steel, these gears are stronger, allowing for higher torque transmission with a lower tooth count.
About the Helical Gears
Helical Gears
High-carbon steel helical gear sets are premium upgrades for RC cars, designed to provide superior strength, smoother operation, and increased durability compared to standard bevel or straight-cut gears. The helical spiral-cut design enhances performance by allowing for better load distribution, reduced noise, and improved efficiency.
Features:
- Precision-machined helical spiral cut gears
- High-carbon steel construction
- Stronger than the stock gears
- More torque can be transmitted through a physical gear with fewer teeth ratio
Includes:
- (1) Steel Helical Cut Rear Ring Gear (30T)
- (1) Steel Helical Cut Rear Pinion Gear (12T)
*Note: It is recommended to use the same type of gears cut style for front and rear.
*Note: Do not use with stock pinion or ring gears with straight cut style teeth.
*Note: Apply a small amount of blue thread-lock on screws and greases on gears.
