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 Suspension's SB042 rear sway bar was designed by factoring in the vehicle weight, application, motion ratio, coil spring rate, and adjustability requirements. Manufactured from heavy-wall 25mm DOM tubing, the SB042 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. The SB042 attaches to your Mustang with fabricated end links and 88-durometer 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 keeps grease in the bushing. The fabricated laser cut, TIG-welded steel sway bar end links are reinforced to minimize deflection. The sway bar is 4-way adjustable to tune the amount of torsional spring rate and to determine the handling characteristics (understeer/oversteer) of the vehicle.
BMR Suspension designed the SB042 sway bar for street performance, drag race, autocross, and road race applications. The large adjustable sway bar has four positions, giving you the versatility to drive to and from the track and still out handle the competition with the same sway bar. The SB042 gives you a 16%-270% increase in rate over the stock bar (depending on year and model). These rate increases and adjustability allow you to fine-tune the handling characteristics of the suspension so you can drive harder through corners with minimal body roll. The hollow design allows for loads of strength without adding a lot of weight. If you're a drag racer, but don't want a solid-mounted antiroll bar on the street, the SB042 is stiff enough to keep the body flat for hard launches and soft enough to maintain streetability. This allows for more sway bar control, which equals better handling. When performance is a must, rely on BMR Suspension!
BMR Suspension's SB042 sway bars are available in black hammertone and red powdercoat for long-lasting good looks. Installation time is about 1-2 hours. Proudly made in the U.S.A.!
