Description

The JBR Tru-Torsion Rear Sway Bar is engineered to significantly reduce the tendency for the front end to push during hard cornering, drastically decrease body roll, and greatly increase traction for the 2010-2013 Mazdaspeed 3. This blade-style rear sway bar is constructed from robust 32mm 4130 alloy steel tubing and features thick solid steel arms. It is precision TIG welded and finished with a durable powder coating available in red, blue, or black. The 3-way adjustability allows for precise handling fine-tuning for both street and track applications. When paired with the JBR Tru-Torsion front sway bar, the vehicle's handling capabilities are transformed. Key features include its design and manufacture in the USA, 4130 alloy steel construction, and the inclusion of stiffer polyurethane bushings with mounting brackets. The kit comes complete with new polyurethane mounting bushings and brackets equipped with grease fittings, installation grease, and installation instructions available in the support section. The product also includes free shipping in the US and a lifetime warranty. Specifications for the 3-way adjustable settings are: stiff setting at 593 lbs/in, stiffer setting at 718 lbs/in, and the stiffest setting at 901 lbs/in.
