QA1 Rear Trailing Arms

QA1 offers upper and lower rear trailing arms for Ford and GM applications in boxed, tubular, and heavy-duty adjustable options. All upper tubular and lower boxed trailing arms use polyurethane bushings on both ends, while upper adjustable and lower tubular trailing arms use a spherical ball or rod end assembly on the chassis end to eliminate bushing bind, allowing the suspension to move smoother for better control. They are powdercoated or zinc plated and anodized for a long-lasting finish. Keep your tires planted firmly on the ground for improved traction and a more predictable, better handling car with a set of QA1 rear trailing arms. Features may include: * Boxed trailing arms are constructed from 0.120 in. wall cold rolled steel tubing for maximum strength and flex elimination. * Tubular trailing arms are constructed from 1 1/4 in. diameter, 0.120 in. wall steel tubing which offers increased strength over other designs, but also have the added advantage of lighter weight. * Boxed and tubular styles feature fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. * Heavy-duty adjustable trailing arms allow easy rear suspension adjustments for optimum handling and traction. Simply loosen the jam nuts and adjust the pinion angle without removing the arms from the vehicle. They replace soft OE differential bushings with polyurethane differential bushings, and they use a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end * Adjustable styles are available in aluminum and steel options

BMR Xtreme Anti-Roll Bars

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.
