My ecx amp had been having shock issues. The front (stock) shocks bind up every time i drive it and when i force the shocks to compress it feels like bound up rubber sliding up and down. Ive tried to open the shocks and fix it but they keep going back to normal when i open them and re fill them. I'm not quite sure what i should do. I dont have much money so whats the best option? Are the 90mm hot racing shocks for the ecx circuit a viable option or should i get the aluminum horizon hobby shocks for my truck? Any other ideas?
