The JAZRIDER front and rear aluminium upper arms are a straightforward durability upgrade for Tamiya Thunder Shot, Thunder Dragon and Fire Dragon buggies. The blue anodised arms replace standard plastic parts to reduce flex and improve part life during normal club runs and practice sessions.
Aluminium resists wear better than injection molded plastic and keeps suspension geometry more consistent under load. These arms are produced to match factory mounting points so installation keeps original alignment and handling characteristics.
Swap the parts using basic RC tools, taking care to torque fasteners evenly. After the first few outings recheck screw tightness and inspect pivot areas for grit accumulation. Routine cleaning will preserve the anodised finish and pivot smoothness.
