Bought struts and shocks for my 2010 4x4. I had the parts on for 2 weeks. I was installing a back up camera and noticed one of the new shocks leaking. I e mailed the company several times about the problem. There reply was I ordered parts for a 2wd truck. Iam a certified tech. I think I know the difference between 2wd and 4wd. They wont do anything to make it right. Horrible business practices with this place. Would not recommend this company at all
