JR-TASB04-BK Rear Knuckle Arms Upgrade for Blitzer Beetle Models JR-TASB04-BK by Jazrider  [JR-TASB04-BK]

Aftermarket rear knuckle arms, black finish

These rear knuckle arms (model JR-TASB04-BK) are a precision-machined black anodized aluminium hop-up intended for RC use with Blitzer Beetle, Stadium Blitzer, and Stadium Thunder vehicles. They replace plastic rear knuckles to provide a firmer pivot point while preserving the original chassis geometry.

Compatibility is restricted to the listed Tamiya-style Blitzer Beetle platforms only; verify the exact model designation when confirming fit. Installation follows the model's standard rear knuckle replacement routine and typically reuses the stock hubs and fasteners if they are in good condition. Inspect pins and screws for wear before refitting.

From a setup standpoint the aluminium construction offers a stiffer pivot than the stock plastic components, which can yield more consistent rear steering feedback and improved durability under demanding driving conditions. Use these arms as part of a broader tuning and maintenance plan for best results.
