FAQ/ABOUT US
What makes your RC differentials different from stock components?
We don’t compromise on durability. Our differential housings are CNC-machined from 7075-T6 aircraft-grade aluminum, which offers incredible structural rigidity and heat dissipation while keeping weight to an absolute minimum. Inside, the gears are forged from heavy-duty Powder Metallurgy Steel (PM Steel), providing exceptional wear resistance and density to handle massive torque. Everything is secured with high-strength alloy steel screws to prevent shearing under extreme stress.
When will I get my order?
We will work quickly to ship your order as soon as possible. Once your order has shipped, you will receive an email with further information. Delivery times vary depending on your location.
How much does shipping cost?
Shipping is free to most regions. Only a small number of countries and territories will be charged a modest shipping fee.
