Blitzer Beetle Aluminum Rear Knuckle Arms JR-TASB04-BK by Jazrider  [JR-TASB04-BK]

Black anodized aluminum rear knuckle arms

These aluminum rear knuckle arms (model JR-TASB04-BK) are a direct replacement hop-up intended for RC-scale use with the Blitzer Beetle, Stadium Blitzer, and Stadium Thunder models. Machined from anodized aluminum and finished in black, they replace the plastic rear knuckles to offer a firmer mounting point for the rear suspension assembly without altering chassis geometry.

Compatibility is limited to the listed Tamiya-style Blitzer Beetle platforms only, so confirm the exact model name when checking fit. Installation follows the vehicle's standard rear knuckle removal and refit process; inspect existing pins and screws for wear and reuse OEM hardware where appropriate. The arms are designed to work with the stock rear hubs and steering linkages on the specified models.

From a tuning perspective these aluminum knuckles supply a stiffer pivot than stock plastic parts, which can translate to more consistent rear steering response during aggressive driving or on-track sessions. They are intended as a durability and minor setup refinement component when used alongside other hop-ups and routine chassis tuning.
