Show original supplier description

The Maximum Motorsports Adjustable Rear Swaybar kit (MMRSB-1 through -9) is engineered to fine-tune your 1979-2004 Mustang's handling balance and extract maximum performance. This system allows for precise tuning to best suit your specific driving style and track conditions. The kit provides a wide selection of bar sizes, enabling adjustable rates that range from softer than a stock Fox Mustang V8 swaybar to up to six times stiffer than the most rigid solid-axle swaybar ever offered by Ford for this generation of Mustang. Multiple sizes are available, including 3/4" x .095" wall, 3/4" x .120" wall, 3/4" solid, 7/8" x .188" wall, 1-1/4" x .095" wall, 1-1/4" x .125" wall, and 1-1/4" x .250" wall. Installation can be performed as either a bolt-in or weld-in process for the chassis mounting brackets. Bolt-in kits require drilling holes in the rear subframe, which may be more challenging on 1996-2004 Mustangs due to structural changes, potentially requiring a right-angle drill motor. Weld-in kits, while requiring welding expertise, offer a lighter and cleaner appearance. The axle mounting brackets for both versions bolt directly to the rear axle housing and do not require welding. This swaybar kit is specifically designed for 1979-2004 Ford Mustangs with solid rear axles.
