Performance Suspension Components
 

I ordered a front end kit from Performance Suspension Components 4-years ago and just got around to installing it. When I put in the lower ball joints the dust boots didn't fit properly. I emailed them with photo's but didn't really expect that they would do much about it, especially since I had purchased the kit 4-years ago. I received a prompt email response from Jerry and he said to return the ball joints and they would replace them. Now that is what I call customer service!

I guess when they say lifetime warranty they mean what they say!
