Pilot RC Products have introduced new X-Rings shock seals for 1/10 Team Associated, Kyosho and Serpent vehicles. Pilot RC team has worked on a solution to avoid swell and deform after just a few hours of being exposed to the silicon oil. The X-ring kit will never swell with the oil and will have a much longer useful life. Throw in the included Pilot Orange grease and they will be performing just like brand new for months! The X-rings are completely able to be wiped off, greased and re-installed time and time again. The kit includes eight X-rings and a sample of Pilot Orange shock grease in a sealing container.
