Review: Quedo perfectamente y funciona de manera optima. - Cambie el piston de aire de mi silla, opte por esta version corta, convirtiendo mi banco en una silla normal. La instalación fue de lo mas sencillo, creo tarde mas tiempo quitando el viejo piston que en poner el nuevo. Su funcionamiento es excelente. En general esta funcionando a la perfección.
