Key Features
- Precision manufactured composite construction — These input shaft cup sleeves are crafted from durable composite material using precision manufacturing techniques, ensuring they meet exact tolerances and deliver consistent performance across multiple uses, which is vital for maintaining smooth drivetrain operation in your RC car.
- Captures input cup screw for maximum reliability — The primary function of these sleeves is to securely capture the input cup screw, preventing it from loosening or shifting during aggressive driving, which could otherwise lead to drivetrain damage or performance degradation.
- Supplied as a set of two — This pack includes two input shaft cup sleeves, giving you a spare pair for replacement or maintenance purposes, which is practical for regular RC enthusiasts who maintain their own vehicles.
- Compatible with multiple ARRMA models — These sleeves are designed to fit a wide range of ARRMA 1/8 scale vehicles including the KRATON 6S V6 4X4 BLX Speed Monster Truck RTR, the NOTORIOUS 6S V6 4X4 BLX Stunt Truck RTR, and the LIMITLESS 8S AVC 4X4 RTR BLX Street Speed vehicles, making them a versatile spare part choice.

Technical Performance
The ARRMA Input Shaft Cup Sleeve (2) Z-ARA311145 represents the engineering excellence that ARRMA brings to drivetrain component manufacturing. These sleeves are fabricated from durable composite material specifically selected for its strength-to-weight ratio and resistance to the stresses encountered in high-performance RC vehicle operation. The composite construction provides several advantages over alternative materials: it offers excellent impact resistance, maintains dimensional stability across temperature variations, and resists degradation from the oils and greases used in RC drivetrain lubrication. The precision manufacturing process ensures that each sleeve meets exact specifications, allowing for perfect fit and function when installed with the corresponding Input Shaft Cup (ARA311144). These components are essential parts of the drivetrain assembly that directly affect the transmission of power from the motor to the wheels, making their quality and durability absolutely critical. The sleeves prevent the input cup screw from backing out or shifting under the intense vibrational and rotational forces generated during acceleration and deceleration cycles in brushless RC vehicles. Whether running a 6S or 8S LiPo-powered ARRMA truck, these sleeves provide the reliability needed for consistent performance whether you're bashing on rough terrain or competing in structured racing events.
