The differential cup, exquisitely crafted from spring steel, boasts high strength and stability, which reduces the impact and pressure on the model car during operation.
Featuring a weight-reducing design, it lightens the weight of the model car. This not only helps enhance the acceleration performance and handling speed of the model car but also improves the power transmission efficiency.
The axle center position, after cylindrical grinding, becomes more accurate, minimizing unnecessary wear and tear while better boosting the performance and durability of the product.
This product is compatible with the original factory part number X3S-04 & X5-27.
