Amazing Customer Service!

When first purchasing the kit, it was very straight forward. I told them what I was looking to do, they directed me to the exact kit with everything needed included.

I recently had an issue with one of the struts, and FIP very quickly responded and handled everything with Silvers. New strut arrived at my doorstep within days.

Highly Recommend ordering with FIP.

Awesome service

Customer service was great. Order shipped quick. Great value and the change to the car was better than expected. Wife no longer braces herself for the expansion joints and other Ohio road issues.
