The XRAY 345620 Aluminum Spur Gear Collar is a direct-fit upgrade created for the RX8e chassis. Built from Swiss 7075 T6 aluminum, this collar combines high strength with low mass to reduce drivetrain play and keep gear mesh stable under load. Its CNC-machined finish ensures accurate seating and repeatable alignment for improved track performance.
Swiss 7075 T6 aluminum is prized for a superior strength-to-weight ratio, which helps the collar resist deformation while keeping added weight minimal. That balance reduces wear on adjacent drivetrain parts and supports more consistent torque delivery.
Whether you are running club races or practising for an event, the XRAY 345620 Aluminum Spur Gear Collar helps maintain gear engagement and drivetrain reliability. It is a sensible maintenance upgrade for racers aiming for smoother lap times and fewer drivetrain issues.
