Kyosho Inferno MP9 TKI4 Hard Rear Lower Suspension Arm Set #IF423HB
These are the replacement Kyosho Rear Lower Suspension Arms included with the TKI4 Buggy Kit. These arms are directional, marked with a "L" and "R", and are made from "Hard" compound materials. Kyosho also offers these arms optionally in standard compound materials.
The lower rear suspension arms benefit from significantly increased webbing around the gussets in the arms. The arms have been reinforced in the web area to make them especially stronger in line with the hinge pin, while still allowing some necessary flex in the perpendicular axis to make shock set-up a LOT easier. Arms that are simply made super stiff in every direction will make the car very difficult to tune properly because thereís such a small tuning window. The TKI4 arms add strength and durability in the right areas, while still providing a car thatís easy to set-up for your conditions and driving preferences.
