Prothane 04 Subaru WRX/STI Rear Sway Bar Bushings - 19mm - Red

If you're looking to tighten up the rear end of your 2004 Subaru Impreza WRX or STI, replacing the stock sway bar bushings is a smart move. These Prothane bushings are made from a durable red polyurethane material that's designed to hold up under stress and reduce the flex you feel when cornering. Stock rubber bushings can get soft and worn over time, leading to a mushy feeling and increased body roll. Upgrading to these 19mm polyurethane bushings will give you a more connected feel to the road.

Polyurethane is a great material for suspension components because it offers a good balance of stiffness and durability. It won't break down like rubber under heat and load, and it resists tearing and abrasion. These bushings are a direct replacement for your factory ones, meaning they fit right into the stock sway bar mounts. The 19mm size is a common upgrade for this generation of Impreza, offering a noticeable improvement in handling without being overly harsh for daily driving.
