The Kyosho IF286 Hard Upper Adjust Rods use durable steel to reinforce the front end on INFERNO R/S and MP9 TKI4 models. They give a firm adjustment point that helps keep suspension geometry consistent across bumpy circuits and high-speed runs.
These rods are intended to substitute existing INFERNO R/S and MP9 TKI4 parts and can replace IFW123 and IFW108 items without special modification. Their form factor ensures they integrate cleanly with the original front suspension layout.
When chasing lap-time improvements, these hard upper rods let racers reduce unwanted front flex and hold alignment better during aggressive cornering. The result is more predictable steering and steadier handling at speed.
