Ordered a set of 5100s online from Top Gun Customz and I was concerned when they showed up as I didn't think they were the correct part number for my 2003 4Runner. I called them twice and spoke to 2 different guys who assured me they were the exact same, just different part # and that they would fit my truck. The part number is for a 3rd Gen Tacoma and I went ahead and installed them today. Well, instead of 2.5" of lift, I think I actually lowered it. Any thoughts???
