GKTech Nissan 240sx/Skyline OEM Rear Knuckle Spherical Bushing upgrade (PAIR) -30.5mm outside diameter spherical bushings (PAIR)

The GKTech OEM Rear Knuckle Spherical Bushing Upgrade replaces the soft, aging rubber bushings in the rear knuckles of S-chassis and RWD Skylines with 30.5mm outer diameter PTFE-lined spherical bearings.
