Whiteline boasts a worldwide reputation as a leading manufacturer of replacement, enhancement and performance suspension components that deliver significant gains in vehicle balance, steering precision, grip levels and outright driving performance.

Consisting of adjustable sway bars (also known as Stabilizer Bars or Anti Roll Bars), chassis bracing, alignment products and chassis control bushing kits, Whiteline products provide automotive workshops, tuners, enthusiasts and racers with innovative solutions to suspension and handling problems while delivering proven performance & problem solving outcomes for many of the worlds vehicle platforms. 

Weight aside, the more the better. Chassis bracing maintains alignment angles and spring rates by greatly reducing body or chassis flex. With regards to undercar chassis bracing, Whiteline engineers have tested and identified up to 15mm body flex on late model vehicles under moderate braking and cornering loads. Chassis bracing maintains alignment angles and spring rates by greatly reducing body or chassis flex. In fact, it helps every component in the suspension system do its job properly. Race cars have elaborate roll cages not just to protect the occupant, a good proportion of its job is to stiffen the chassis. That’s why it triangulates and links every major chassis and suspension pickup point with each other. Critical for serious performance and essential for any car with uprated springs, shocks or swaybars.
