These are direct replacements for your OEM steering rack bushings which are soft and will create excessive movement over time and mileage which will hinder driving feedback from the steering wheel.
The Whiteline units will provide a better initial turn in and an overall better driving experience.
Please note that with any harder bushings, there will be a slight increase in noise and vibration.
Hardware, along with a tool will be provided to make these bushings ready for the installaiton.
