These RC-scale replacement pins and C-clips are made for C-clip style double-joint universal (W/J) assemblies in BD7-style on-road drivetrains. The items secure the double-joint while allowing rotation and preventing axial movement, forming a simple but vital part of routine upkeep and repairs.
Use the components only on the chassis variants listed below where the C-clip joint is specified. When removing or fitting the C-clip and pin, employ fine pliers and avoid deforming the clip or bending the pin, as either will introduce driveline play.
When diagnosing driveline vibration, binding, or endplay, check these fasteners; replacing worn pins or fatigued C-clips helps maintain correct drivetrain alignment and reliable wheel response.
