Replace your flimsy, imprecise OEM sway bar end links with 034 Motorsport performance-engineered adjustable spherical end links! 034 Motorsport's Billet Adjustable Rear Sway Bar End Links allow for the uncompromised transfer of suspension energy and movement to the sway bar.  With its adjustable length design, the 034 Motortsport Billet Adjustable Rear Sway Bar End Links allow you to maintain proper preload on the sway bar when lowering your car.  034 Motorsport sway bar end links are the only options on the market with high misalignment sphericals, ensuring that the end links do not bind as the suspension articulates.  In addition, adjustable sway bar end links allow you to adjust preload on the sway bar, as well as alleviate potential sway bar clearance issues caused by lowering your car.

When a sway bar is preloaded, it means that it is already twisted when the car is at rest, and it‚¬„¢s trying to roll the car to one side because of this.  This will lead to asymmetric behavior and the car will favor tuning one way versus the other.  Preload is detectable when the car is at ride-height on a flat surface, and removal of an end link is difficult because the sway bar is already twisted and applying force on the bolt, or installing the end link is difficult because the bar needs to be twisted to insert the bolt through the hole in the sway bar.  With equal-length non-adjustable sway bar end links, removing preload is not possible.

By utilizing our 034 Motorsport adjustable end links, the lengths of each end link can be adjusted so that the end link can be easily installed at ride height without needing to twist the bar to get it to fit.  Zero preload provides symmetrical handling in right and left turns.
