When installing new components, it's always a good idea to replace the associated hardware to ensure proper tightening and fitment. This kit includes all the necessary hardware for the front control arms, per side. If you're performing a overhaul of your control arms, or just want to replace the hardware, this kit was made just for you, so there's no need to about stripped bolts and nuts.
This kit only includes the securing hardware for one side, meaning that two must be purchased for a complete set.
