H&R Rear Sway Bar 25mm Adjustable Subaru 2004-2007 STI

Both professional and amateur racers agree, upgrading the sway bars on your STI may be the single most effective suspension modification. H&R Sport Sway Bars are crafted from the highest tensile strength steel available, a proprietary (hf) 50CrV4 steel alloy. This design guarantees a smooth transitional sway bar function, decreasing feedback response time and increasing stiffness. H&R Sport Sway Bars will reduce body roll while improving lateral stability and cornering grip. Adhering to the same manufacturing philosophy as H&R’s world-renowned springs, each H&R Sport Sway Bar is cold-formed and heat-treated. Before testing, the H&R shot-peen process ensures durability and dimensional accuracy. In addition, each H&R sway bar will endure a series of rigorous quality control tests, ensuring that all finished products meet the high standard you expect from H&R. All H&R Sway bars include their exclusive urethane/Teflon grease-less composite sway bar bushings.
