Mine is the LRE, rubber equalizer, and it does very well. The 5er is a RK and nothing bounces around and everything stays put on the counters. Very happy with it. I'm putting on Trailair airbag equalizers and pin for a friend this weekend on a Fuzion TH. The problem is... he wants to do it as soon as the 5er is delivered to his house. I cant talk hin into towing it first and doing one change at a time to see how they do. Craig
