A good way to find out if yours has them or not would be to stick your head under it and HAVE A LOOK ffs. Better on the road with em, better off the road without. Simple as that.
My 300tdi ended up potentially dangerous as a result of leaving the rear anti roll bar in place after a 2" lift
The problem was that one side of the anti roll bar would filp upwards and end up sitting uneven making the car sit on the **** ........ removal of the A.R.B was the best cure
