This 6g steel weight is designed for mounting at the rear R upper suspension arm point on 1/10 YZ-2 2WD off-road models. It relocates a small mass toward the rear upper link to help tweak balance and transient reaction while leaving suspension geometry intact.
Installation is straightforward: the single-piece weight secures to the rear upper arm mount and acts as a compact tuning mass on the R upper link assembly. Because the item is small, changes are subtle and aimed at tuning feel rather than major setup overhaul.
