This aluminum bushing set is engineered to upgrade the throttle and brake linkage system on Kyosho Inferno MP9 series vehicles. By replacing the standard plastic bushings within the servo horn with precision-machined aluminum components, it significantly reduces play and slop, thereby enhancing the directness and responsiveness of throttle and braking inputs. This upgrade not only provides more consistent and precise control for competitive racing but also increases the overall durability and longevity of the servo horn assembly, ensuring reliable performance under demanding conditions.
