Please ensure your correct model is selected

The next step in tuning your car's handling - after shocks/springs and camber plates - should be a set of swaybars. Using larger front and rear sway bars will give your car better/quicker turn-in and less bodyroll in corners. These bars replace the existing sway bars on the car for a clean and simple upgrade with very little downside. Sway bars should be matched with your springs/shocks to maintain a proper handling balance. In some cases only a front or rear bar is needed to positively change the balance and make the car more neutral. We sell sway bar kits from H&R, Racing Dynamics, OE BMW upgrades, and even some of our own designs. Swaybars are sold with new bushings. New links and other hardware are strongly recommended.

Lowering your BMW does wonders for appearance and handling, but it also changes suspension geometry in ways that can hurt performance. As ride height changes, angles between the sway bar, control arms, and axles shift, which can cause binding, poor fitment, and added stress on the factory fixed-length end links. This is especially noticeable on cars equipped with coilover suspension, where slight height differences side to side can preload the sway bar and lead to inconsistent handling.

Our team of dedicated BMW enthusiasts set out to address this common issue with Adjustable Rear Sway Bar End Links. Designed with performance in mind, they offer a fully adjustable range from 100mm to 120mm, helping eliminate preload, restore proper suspension alignment, and improve overall sway bar function. Constructed from high-quality billet aluminum, these end links are built to outlast the factory cast components and are finished with a black anodized coating for excellent corrosion resistance. Laser-etched wrench size markings allow for quick, easy adjustments while installed on the vehicle. Unlike the factory design, these end links use spherical rod ends at the control arm for increased responsiveness and a more direct handling feel. These end links feature a bolt-through bushing design, which is compatible with most adjustable aftermarket sway bars. Mounting hardware is included for easy installation.

Features & Benefits:

Adjustable from 100mm to 120mm Strong 6061-T6 billet aluminum construction Black anodized finish resists corrosion Spherical rod ends improve response and handling feel Polyurethane bushing with knurled bore helps retain grease Fits most aftermarket sway bars with bolt-through attachment Laser-etched markings for quick and easy adjustments
