steering dampners

Hi all probably been asked before, have to replace the dampner on my 89 hilux d/cab solid front end have asked TJM they recomend the type with the spring on it (return to center) as the one to go for $170 ARB reckon there a waste of money as the dampner becomes smaller because it has to go inside of spring due to restricted room where it mounts there fore not as good where I could get one without the spring and have a bigger dampner, confused which way to go. See a lot of patrols etc with the spring seems very popular ???? Any help would be appreciated before I waste money on somthing I dont need. The one I have now is still the standard one from toyota but is stuffed (bent). Thankyou
