Improve handling and eliminate sway bar preload with aFe Control’s adjustable end links. Sway bar preload is a scenario where your sway bar is in tension when your car is at rest. Sway bar preload affect’s how the vehicle handles making it stiffer when turning one direction versus the other. Factors like lowering springs can end up with uneven suspension heights which can lead to sway bar preload. If you have adjustable coilovers and are corner balancing the vehicle, it is especially important to zero out your sway bar preload to get consistent handling. Made with high quality Aurora rod ends and precision machined adjusters, these end links will make short work of dialing in your suspension. Joint articulation was designed to exceed factory range which prevents binding during operation. Equipped with right-hand and left-hand rod ends, the end links can be adjusted on-car without removal. Whether you’re setting your car up for the street or track, aFe Control will get you there! Our adjusters are CNC machined out of 6061-T6 aluminum and anodized blue with laser etched logo. For superior quality and reliability, we use PTFE lined Aurora rod ends. aFe CONTROL Front Adjustable End Link Set Blue BMW M2 (F87) 15-21/M3/M4 (F80/82/83) 15-20 L6-3.0L (tt) N55/S55 BMW M2 (F87) 15-21/M3/M4 (F80/82/83) 15-20 L6-3.0L (tt) N55/S55
