This RC-scale upgrade set includes two red aluminum upper suspension arms made to replace the stock plastic pieces on Tamiya Thunder Shot, Thunder Dragon and Fire Dragon chassis. The stronger mounting points help reduce unwanted flex and produce a firmer, more predictable suspension response under load.
These arms are intended as direct replacements for the listed Tamiya models and normally use the existing fasteners and linkage hardware where compatible. Check fitment at each attachment and re-torque connections after installation; reuse stock ball studs and pins unless your chassis manual recommends upgrades.
Designed as a tuning component rather than an electronic or drivetrain change, the arms assist with keeping camber consistent and stabilizing roll during cornering when paired with an appropriate shock and tyre setup. Sold as a pair for RC buggy use only.
