MIP Pro-MT 4×4 HD pivot ball set

Made for Pro-Line’s Pro-MT monster truck is a new pivot ball set from MIP. They were designed to replace the standard items with sturdier and more durable ones, doing away with breaking issues associated with the original PL parts. MIP increased the diameter where the shoulder and threading meet for increased strength as well as manufactured these pivot balls using high impact alloy steel. The suspension balls are direct replacements and they come in sets of two.
