This alloy rear suspension arm set is an RC-scale replacement part suited to the Blitzer Beetle family, including Stadium Blitzer and Stadium Thunder. Machined in a gun-metal finish, these arms replace stock plastic pieces to provide a firmer rear mounting point while keeping the original chassis geometry intact.
Use and fitment: produced for 1/10-scale Blitzer-series Tamiya platforms, these parts act as direct hop-ups to stiffen the rear pivot and alter how the chassis responds under acceleration and on rough terrain. Confirm fit on your vehicle before final installation, since slight differences in shock towers or hinge-pin spacing may require minor adjustments.
Installation guidance: remove the factory rear arms and inspect hinge-pin bores and surrounding mounts for wear. Fit the aluminum arms in the same orientation as the originals, check hinge-pin alignment, and verify that travel and droop remain correct. Tighten fasteners progressively to avoid misalignment, then re-check after a short run. These arms are maintenance-friendly but work best with well-tuned shocks and inspected mounting hardware.
Tuning notes: because aluminum reduces flex at the rear pivot compared with plastic, expect subtle shifts in traction and throttle feel. If the car becomes twitchy during quick direction changes, try incremental increases in rear damping or small roll-center changes to rebalance handling. For bump compliance, ensure shock lengths and spring rates suit the stiffer mounts.
