Same brand, that is a new one that was in the shed as a spare. Never even scratched the control knob they seem to stay out of the way.
When new the bush is so thick it took some effort to get the nut started, after some use it probably wont be a problem untill replacement time.
Wieghed the ute loaded for an outback trip with 8 gerrys full of fuel / water etc then gave the axle wieghts to a spring mob and said design a system around that.
It sits nice and handles just as well. Have a speed bump in our village here 50kph speed limit smooth as, empty or full. Very well matched package I ended up with.
