BMR Xtreme anti-roll bars feature a massive diameter and include heavy-duty rod ends. These sway bars have an easy bolt-on design with the option to be welded, if desired. The factory rear sway bar works well for handling, but falls short when it comes to drag racing. There are two main reasons for this—the OE bar diameters are nowhere near the right diameter to control torque loading on a launch, and the OE-type bar only attaches at the control arms with no frame attachment points. This allows for too much body separation and no way to control it. By attaching the end links to the frame, body separation is minimized and converted into forward momentum. This, combined with the large diameter bar's ability to better control torque loading, creates more consistent and predictable launches and better 60 ft. times. BMR Xtreme anti-roll bars come with all necessary Grade 8 mounting hardware.

One of the most effective ways to improve the stiffness and handling of your vehicle is to box the factory chassis. Hellwig Frame FX kits makes it easy for you. Rather than taking considerable time with measuring, cutting, and fitting steel panels these kits simplify the process effectively. Some vehicles have an open C-channel chassis that's only 3 in. wide at the top and bottom. This design is inherently weak in handling torsion and marginal in bending. Frame FX kits double the width of the tension side of the frame rail and close the area for dramatic increases in torsional and bending stiffness. They're comprised of 14 pre-cut 10-gauge steel panels matching the thickness of the factory frame--and fit into the weak points of the factory chassis. Hellwig engineered another panel that adds an extra mount to tie the floor to the chassis, furnishing even more strength to the entire car. In addition, brackets are provided to mount the transmission crossmember, with enough adjustment to accommodate nearly any drivetrain configuration. The increased strength via Hellwig Frame FX kits results in improved handling and ride quality, while retaining the factory chassis and mounting points.

Most vintage OEM front sway bars were calibrated with tires and cornering loads that were radically less capable than today. Ride Tech increases the diameter of the sway bars to minimize body roll through the corners and optimize handling. Incorporated into the polyurethane frame bushings is a Delrin insert to eliminate stiction and allow the sway bar to move freely and improve ride quality. In addition, many stock sway bar designs create bind and poor sway bar geometry when the vehicle is lowered. Ride Tech's beefy end link-style StreetGrip sway bars eliminate that bind, correct the geometry, and reduce body roll. Where applicable, adding a rear sway bar drastically decreases body roll and increases stability. RideTech StreetGrip rear sway bars are a direct bolt-on to your OE suspension or as part of a complete StreetGrip suspension package.

Sway bars are principally designed to reduce body roll or sway. By reducing body roll, lateral loads are spread more evenly across the tires, resulting in increased cornering grip and improving outright performance. Nolathane sway bars give you more grip, which produces better handling, translating to improved outright performance. Upgrading the sway bar is the best dollar-for-dollar handling improvement you can make to your vehicle. Added benefits extend to improvements in handling, safety, and tire wear without affecting ride quality or comfort.
