When it comes to cars i dont think cheap is the way to go. I hear many people who by ebay parts then 2- 3 months down lthe line its broke. Being that it deals with your suspension i wouldnt trust it at all. Hooking up a car is expensive not cheap. Just make sure you do it right. I could cost you much more for buying the cheap ones as suppose to getting the real ones.
