Description
SPL Parts 2014+ Infiniti Q50 / 2017+ Infiniti Q60 Rear Swaybar Endlinks is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from 2014+ Infiniti Q50 / 2017+ Infiniti Q60 Rear. SPL Parts focuses on competition-grade suspension and alignment hardware, combining in-house development with U.S.-sourced materials and precision manufacturing for demanding street and track applications.
These adjustable sway-bar end links create a more direct connection between the anti-roll bar and suspension while allowing link length to be set for the vehicle's actual ride height. Correct end-link length helps remove unwanted anti-roll-bar preload at static ride height, so left-to-right response is more symmetrical and bar rate is delivered more consistently during cornering.
Why it matters: On this application, the goal is to keep the tire and upright closer to the intended alignment as loads rise, giving the driver a more repeatable platform for braking, turn-in, mid-corner balance, and power application. Lower-compliance joints also sharpen transient response, making this a useful supporting modification for coilovers, adjustable bars, corner balancing, and track alignment work.
After installation, recheck fastener torque and alignment after the initial heat cycles or track use so the setup remains repeatable.
