Dialing in your suspension on the Subaru WRX is very important to achieve ultimate handling. With all wheel drive cars, getting the proper balance of over and under steer will enhance your cars handling performance. The factory rear WRX sway bar links from 02 and on are a urethane material that flexes heavily under load. Agency Power has redefined suspension handling with these replacement rear sway bar links. These links will stiffen up your rear end of the car and give you the proper handling you need. The Agency Power Subaru WRX rear sway bar links are CNC machined 6061 aluminum that is to the exact same specs as the factory for a no hassle fitment. Unlike the competition, the AP sway links are much thicker for strength. The end links include monoballs that are sealed and held in place with C Clips. This allows you to clean and maintain if necessary. As well, the AP links include high strength steel hardware, stainless steel collars, and nylon locking nuts for a secure fit. Each end link is lasered with the AP logo and sold as pairs in the AP Speed Red color.
