This is a polyurethane steering rack bushing kit for the Nissan 240SX and 300ZX.
It is a 3 piece kit, however you only use two depending on your chassis.
The stock bushings are rubber, and most likely they are dry rotted making the steering feel sloppy.
Worn rubber bushings will have the same sloppy effect.
The polyurethane bushings are much more rigid then the rubber, and will make your steering more responsive and more direct by holding the rack in place.
Installation is very straight forward, and fairly easy.
