i have a 'Quicke'/ALO brand loader on my machine. i got the 'soft ride' option. It's a hydraulic accumulator on the lift circuit. operates with an manila shut off valve to isolate it. I took delivery before it arrived and installed it myself after, took all of 5 minutes.
It does help on the road (i road a lot). with some of the bouncing. It does make precise movements of the bucket impossible. but when you know ya gotta. load something on a 1/2 ton box you shut it off and carry on.
was it worth $1000? probably not. Is it nice after adding it? Yes. would i but it again? probably not, but maybe.
