Designed for Vehicles / Universal (no vehicles listed)

These sway bar links work with the S4 FC3S control arms, which are preferred over the S5 control arms because they have replaceable ball joints.

Replace your worn stock sway bar (also known as a stabilizer bar or anti-roll bar) end links with these adjustable links made by Improved Racing. Lowering a vehicle or adjusting corner weights often results in undesired sway bar preload, negatively affecting the vehicle's handling. These links allow you to eliminate preload and properly corner-weigh your vehicle. Links can also be made shorter than the stock links, which is ideal for lowered cars with limited ground clearance.

This high-performance kit features high-quality, 3-piece rod ends made in the USA by FK Rod Ends. These motor sport grade rod ends are built to tighter tolerances and last longer than standard rod ends.
