Blitzer Beetle Rear Knuckle Arms Upgrade - JR-TASB04-GU for Blitzer Beetle, Stadium Blitzer, Stadium Thunder by Jazrider  [JR-TASB04-GU]

Upgrade rear knuckles for Blitzer models

This RC-scale aluminum rear knuckle arm set replaces stock plastic components on compatible Blitzer models. The gun metal anodized finish and machined aluminum construction improve wear resistance and keep steering geometry stable under load, making these arms a good choice for hobbyists wanting a firmer rear steering mount without altering drivetrain parts.

Installation is straightforward for users familiar with standard Tamiya-style rear hubs and C-clips. The arms act as a tuning upgrade to reduce hub flex and help preserve toe settings during hard cornering and jumps, while retaining original mounting points so camber and toe adjustments remain usable.

The knuckles provide a conservative tuning path: they stabilise rear steering inputs, help maintain consistent tyre contact during dynamic manoeuvres, and offer a durable alternative where stock plastic can deform over time.
