Blitzer Beetle / Stadium Rear Knuckle Arms JR-TASB04-DB Aluminium Dark Blue upgrade for compatible models by Jazrider  [JR-TASB04-DB]

Rear Knuckle Arms for Blitzer Beetle and Stadium Variants

The JR-TASB04-DB rear knuckle arm set is crafted from aluminium and finished in dark blue anodizing to offer a hard-wearing replacement for plastic stock parts on Blitzer Beetle and stadium chassis. These machined arms are intended to provide greater durability and reduced flex in the rear suspension linkages.

Fitment relates to models that share the same rear hub spacing and mounting points as the Blitzer Beetle series and its stadium counterparts. Verify pivot and hex arrangements on your chassis before fitting. This upgrade is supplied without bearings, pins, or screws as it is sold as a small parts hop-up.

Installation steps: remove the rear hub per the chassis manual, transfer any bearings or liners from the original knuckles where required, then attach the aluminium knuckles with existing hardware. Check for full travel and ensure no binding occurs at travel extremes. Using a light thread locker on metal fasteners is optional for high-vibration setups, and avoid over-torquing to preserve pivot motion.

Tuning note: replacing stock plastic knuckles with aluminium reduces component flex, which can stabilise rear toe and camber under cornering loads and yield a more predictable handling response; adjust shock and tyre choices accordingly to match the new behaviour.
