When discussing anti-roll or stabilizer bars, many driving experts consider factory stock end links to be the "weak links" in the system, with a tendency to bend. Often, they'll upgrade to these heavy-duty Whiteline sway bar end links to eliminate preload via the adjustable center-to-center length feature. Many Whiteline models are constructed with aluminum bodies and heavy-duty steel ball joint ends that not only adjust, but also rotate to any angular combination. Bottom line: stronger end links equal improved suspension and handling.
