Improve cornering control and component life with the GPM alloy rear upper arm bulk specified for Kyosho Mini Inferno ST, Mini Inferno, and Mini Inferno 09. Built from quality aluminum, the part adds stiffness where it matters and reduces chassis deformation under load.
Aluminum combines low weight with high rigidity, making it ideal for upgrade parts. Installing an aluminum rear upper arm bulk can reduce flex and provide more predictable handling across chip, gravel, and tarmac sections.
