I have there "K" member , it is excellent! why .. well 1st the price, 2nd was what i was buying it for: access to my headers, block and such from under the car. 3rd weight shaving. I have MM pretty much everything... but the UPR was lighter than the MM "K"member. and alot less. As far as my experiance with Customer service, well it was great, i order my "K" member and it was at my door in 4 days. I live in CT UPR is in WPB, Florida. Another thing is when i was installing the "K" member its was on a Sunday, i called left a message, thinking that they were going to call me back on Monday, nope a tech was there and called me back.. (SUNDAY)
I give them 5* for their service... 5* for the quality of the bump steer , "K" member and "A" arms
