    I do not know about now, but when the LR4 first arrived in Australia, the blokes were changing out the factory LR4 air bag and shock assemblies for factory LR3 units.

    The spring rates or whatever were / are different at the time of introduction and the perception was that the LR3 units were better tuned for rough conditions.

    Me, I would be installing LR3 units unless I was looking for the boulevard ride, and then it would be on all four corners.

    That's an interesting note I had not heard of before. Makes sense why the lr4 feels a lot more dampened if it's not simply due to the geometry and few small parts in the front end suspension.

    My view is that the LR4 is tuned for pavement more so than what the LR3 ever was.

    I find that on what I call corduroy - that is lots of smaller regular recurring bumps, (including railroad tracks), that the LR3 is superior to most. It is certainly better than an F-150 or most pickups. Those vehicles tend to go sideways when the road is rough whereas it seems the faster one goes in the 3, the more stable it is.

    Locally there is a main rail crossing with 3 sets of tracks. I can go over them at speed whereas most vehicles slow to a crawl. Even then, snow lumps frozen to the suspension gets thrown off even at a crawl. My problem can be not remembering to slow down if following the pack.

    That was pretty much what the problem was in Australia; on rough roads, the 3 just drove better than the 4, and hence where it mattered, the owners installed the LR3 airsprings in their new 4's.

    I think you can pull some interface parts off an old rear strut but having gone through this, I'd just go with the oem or factory parts like seen on Rovers North.
