Description

The BMR Suspension Rear Sway Bar Kit (SB045H) is engineered to significantly reduce body roll and enhance the adjustability of your 2015-2023 S550 Mustang's suspension. Unlike stock sway bars, which often use smaller diameter bar stock or tubing leading to low torsional spring rates, BMR's kit utilizes a 25mm heavy-duty bar stock construction for superior strength and cold-formed properties to better resist torsional fatigue. This kit is designed for street performance, autocross, and road racing applications, offering a 63-208% increase in sway bar rate. It features 88-durometer, greaseable polyurethane bushings with zinc-plated inner sleeves for durability and smooth operation. The three-way adjustability allows for precise fine-tuning of your Mustang's suspension to suit various driving conditions, leading to improved handling and a more responsive feel, likened by users to driving a go-kart. Installation is estimated to take 1-2 hours.
