Description
This is a set of 2 reformulated front HD lower hinge pins for the Inferno MP9 TKI4. With the increased strength of the new MP9 TKI4 lower suspension arms the pins also needed some re-thinking. The correct balance of metallurgy was required to create the best balance between hard (brittle with the tendency to break) and soft (with the tendency to bend). Kyosho’s 30+ years of racing experience and Yuichi Kanai’s testing and tenacity to get it right come into play here!
