This Upright is an RC-scale replacement steering knuckle offered under the Serpent 440118 designation and intended for use with the Mini Spyder Monster truck RTR EP model SER440001. It serves as the front suspension steering connection, locating the wheel hub and transferring steering inputs to the wheel.

The article focuses on compatibility and functional role rather than material specifications. Fitment is specified for the Mini Spyder platform SER440001, so verify the part number against your truck before ordering. When replacing an upright, confirm hub alignment, secure existing fasteners, and check wheel bearing seating to maintain predictable steering geometry.

For tuning and setup, uprights affect scrub radius and steering response; small changes to upright condition or mounting can alter wheel toe and steering feel. Use this part as a direct-replacement component to restore original steering geometry or as a service item during routine maintenance.
