Blitzer Beetle Rear Knuckle Arms Aluminum Dark Blue JR-TASB04-DB for Stadium Blitzer and Stadium Thunder by Jazrider  [JR-TASB04-DB]

Upgraded Rear Knuckle Arms for Blitzer Beetle Range

This JR-TASB04-DB rear knuckle arm set is a machined aluminum replacement made for the Blitzer Beetle family and related stadium chassis. The pair is fabricated from aluminum and finished in dark blue anodizing to resist routine wear. Designed as a durable hop-up for rear suspension linkages, these knuckles replace the stock plastic pieces to keep suspension geometry consistent under load.

Compatibility covers models that share the same rear hub dimensions and mounting points as the Blitzer Beetle and its stadium variants. Before installing, confirm your chassis uses the same knuckle pivot and wheel hex arrangement to ensure correct fitment. These items are sold as a small parts upgrade and do not include ball bearings, pins, or screws.

Installation notes: remove the rear hub assembly following your chassis manual, transfer any bearings or inserts from the original knuckles as needed, and secure the aluminum knuckles with the existing hardware. Confirm full steering travel and that no binding occurs at the extremes of suspension movement. A light application of thread locker on metal-to-metal fasteners is optional for high-vibration use, but avoid over-tightening so pivot action is preserved.

Tuning role: swapping to aluminum rear knuckles reduces flex compared with stock plastic arms, which helps stabilise rear toe and camber under corner loads and produces more predictable handling during aggressive throttle or braking on tight tracks. Use these arms as part of a measured tuning approach, pairing them with appropriate shocks and tyre choices to balance overall grip.
