This is a Yeah Racing newly designed damper set for 1/10 RC cars. Despite the 5 stage stiffness spring sets, Yeah racing damper set featured the state of the art technology interchangeable damper piston which gives so much serious tuner so much potential to tune their damper settings. The interchangeable piston will allow 3 settings of damper's response as well as 4 rebound rate adjustment to fit different racing situation and maximum performance. The Yeah Racing new damper set has spent great effort on increasing the durability and maintenance ease. The damper shaft is coated with titanium for minimizing friction and longer lifespan. To cope with the need to change the damper piston from time to time, the shock gear have selected premium quality anti-leak O-Ring to keep the damper oil in place. CNC machined high grade aluminum were used to build this high end damper set for maximum durability at the minimum weight.
