Overview

The BMR Suspension SB043R is a front 35mm and rear 25mm sway bar kit constructed from heavy-duty DOM steel tubing, cold-formed and CNC-formed for precise fitment and durability. It includes 88-durometer, low-deflection polyurethane bushings to reduce deflection compared to stock rubber bushings. This kit is designed for enhanced street performance, autocross, and road racing, offering a significant increase in sway bar rate (19%-55% front, 63%-208% rear) for fine-tuning handling characteristics and minimizing body roll. The hollow design provides strength while keeping weight down. It is available in black hammertone and red powdercoat finishes. Installation is estimated to take 2-3 hours. Proudly made in the U.S.A.

Part #: SB043R

The two primary functions of sway bars are to control body roll and to determine the understeer or oversteer behavior of a vehicle. Stock sway bars have low torsional spring rates because they are manufactured from small diameter bar stock or tubing. BMR Suspensions SB043 front and rear sway bar kit was designed by factoring in the vehicle weight, application, motion ratio, coil spring rate, and adjustability requirements. Manufactured from heavy-duty 35mm (front) and 25mm (rear)DOM steel tubing, the SB043 is cold formed to better resist torsional fatigue and retain its "memory" far longer than the hot-formed bars used by many competitors. The sway bar is CNC-formed for exact manufacturing tolerances and repeatable high quality.Thrust washers are welded to the front bar to locate the sway bar bushing mounts. This is critical as it properly locates the sway bar and prevents lateral movement during hard cornering maneuvers The SB043 attaches to your S550 Mustang with polyurethane bushings, reducing the deflection from the stock rubber bushings. These bushings are molded from 88-durometer, low-deflection, polyurethane, and are internally fluted to keep grease in the bushing.BMR Suspension designed the SB043 sway bar kit for street performance, autocross, and road race applications. The large adjustable sway bars three positions give you the versatility to drive to and from the road course or autocross and still out handle the competition with the same sway bars. The SB043 front sway bar gives you a 28%-70% increase in sway bar rate, and the rear bar gives you a 63%-208% increase in rate over the stock bar. These rate increases and adjustability allow you to fine-tune the handling characteristics of your S550 Mustang so you can drive harder through corners with minimal body roll. The hollow design allows for loads of strength in the lightest package possible. This means increased performance with no sacrifices.
