Guy seemed to think they were just reman'd. Looks like they used to be, but at some point Arnott introduced completely new NON-reman ones. For $4XX, that seems a lot better than $1300... I watched a couple youtube videos on replacing them, and it really doesn't seem like 3 hours... hour at most with proper tools and a lift. This shop has great reviews (insanely great, actually) and comes highly recommended... but maybe they're just not aware of Arnott's non-reman option. Example thread: http://www.rangerovers.net/forum/6-range-rover-mark-iii-l322/253041-best-pricing-arnott-expedited-parts-brand-struts-2.html. Doesn't seem like they had the best rep as of two years ago. From best I can tell, these 'new' options have only been on market for a year or less.Arnott struts are great. In over 10 years of using them i have only had to warranty 1 and it was many years ago. Arnott uses a much better quality air bag than the factory.
I just replaced both rear on mine (2007 Sport SC without Stability) around 3 hours of labor. I bought them at Rover Land Parts:
