Parabolic springs on an ambulance?

I have a Marshall bodied ambulance with tired springs and I am considering fitting parabolic springs which I assume would improve the ride. It is fitted with anti roll bars for good reason and I wonder if it's possible or desirable to retain them with parabolic? Any advice appreciated.

Parabolics normally rsult in more body lean as they are more compliant than regular leaf packs. Anti-roll bars would be a good idea with them.

May well be worth having a word with GB springs at "www.gbsprings.co.uk" They do five leaf parabolics.

Getting the right spring rate is important. Too heavy a spring rate and the parabolics will ride and flex worse than a regular leaf pack. Personally I'd prefer a softer spring and anti roll bars over a stiff spring and a poor ride.

Many thanks all. I knew that there wouldn't be a clear winner but I shall consult GB Springs. I still be interested to hear from anyone who has fitted parabolic springs to a series ambulance Land Rover
