Description
The two primary functions of anti-roll bars (sway bars) are to control body roll and to determine the understeer or oversteer behavior of a vehicle. Stock anti-roll bars have low torsional spring rates because they are manufactured from small diameter bar stock or tubing. BMR Suspension’s SB042 rear anti-roll 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 anti-roll 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 moulded from 88-durometer, low-deflection, polyurethane, and are internally fluted to keeps grease in the bushing. The fabricated laser cut, TIG-welded steel anti-roll bar end links are reinforced to minimise deflection. The anti-roll 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 anti-roll bar for street performance, drag race, autocross, and road race applications. The large adjustable anti-roll bar has four positions, giving you the versatility to drive to and from the track and still out handle the competition with the same anti-roll 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 anti-roll bar control, which equals better handling. When performance is a must, rely on BMR Suspension!
BMR Suspension’s SB042 anti-roll 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 USA!
