Kyosho Big Bore Shocks!!Revered as the best 1:8 scale shock that exist today. Incredible performance as well as the longest lasting in the industry as well. With an incredible array of options they are the most tunable as well! Some of racers asked for the treaded shock bodies, and here they are! No longer do you need to use the plastic spacers like on the older shocks. Some of us like this and some prefer the spacers, but now we have a choice!
