GKTech Scion Subaru Toyota FR-S / GR86 / BRZ rear knuckle traction arm spherical bushings

The GKTech Rear Knuckle Traction Arm Spherical Bushings replace the soft, factory rubber bushings found where the traction arms mount to the rear knuckle on the FR-S, GR86, and BRZ chassis. These PTFE-lined spherical bearings eliminate unwanted movement and flex in the suspension under acceleration, braking, and cornering—resulting in improved rear-end stability, alignment consistency, and sharper handling response.

Engineered for direct press-in fitment, these bushings are ideal for drift, track, or spirited street driving where precision matters. They’re a perfect match for cars running adjustable rear arms or looking to tighten up the rear geometry for more predictable behavior under load.
