I have had this 700 R4 since 1992 hooked up and it drives great. It does lock up at 45 MPH if the switch is on. It does unlock at 45mph are less with it on. I don't know what my right foot has to do with it locking up though? It want lock in any other gear that I know of. The truck drives fine well since 1992 it has. It stops just fine.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
