Agency Power has redesigned the Subaru WRX 5 Speed Shifter Bushings to be the dominant transmission enhancement. Unlike the competitors, we use a nylon material which is much stiffer than the factory and urethane. The nylon shifter bushings are a direct replacement for the factory bushings giving each shift a firm and responsive feel. Shifters bushings work great in conjunction with our Agency Power 5 Speed Short Shifter. Sold in pairs and available in white only.
