Technical Performance
The ARRMA Input Shaft Cup Sleeve represents the engineering excellence for which ARRMA has become renowned in the competitive RC market. Manufactured from engineered composite material, these sleeves provide the rigidity and durability required to handle the extreme torque and rotational speeds generated by 6S brushless motor systems. The composite construction offers several distinct advantages over alternative materials: it provides excellent dimensional stability across varying temperature ranges, maintains consistent performance throughout extended driving sessions, and resists the corrosion and wear that can occur with exposure to dirt, moisture, and the occasional water splash typical of outdoor RC driving. The precision manufacturing process ensures that each sleeve meets exact specifications for diameter, wall thickness, and internal geometry, preventing issues such as excessive play in the transmission or misalignment of drivetrain components. When used in conjunction with the compatible Safe-D input gear (ARA310977), these sleeves create a transmission assembly capable of handling the demanding requirements of high-performance brushless RC trucks, buggies, and speed vehicles. For users of ready to run RC cars UK and dedicated bashers alike, maintaining a supply of these genuine OEM parts ensures your vehicle remains in peak operating condition and ready for action whenever you are.
