As a Jaguar, Land Rover master tech for 25 years I have installed many air spring conversion kits. All by Arnott with no fitment issues. I decided to try this kit on my personal Jaguar XJ. The price was about the same, however I liked the color choice. Jaguar uses yellow bilstein shocks on the performance models, svr etc. These came plain black, springs, and shock with only a red boot. Now let's talk fitment... rears were fine. The front are terrible. The lower control arm attachments are spread open too much and not parallel. This means the supplied bolts will not start correctly. I used very large Channel locks on the first installed 1 to squeeze together to be able to start the bolt the bolts are also too long and once tight hit the front control arm which not only binds it, but you won't be able to install this front arm without backing out the bolt. Need to either shorten and chamfer the bolt, or grind clearance. Overall I would not recommend this kit because of this, no cost savings, and item is not as pictured. I work on lift and fully equipped shop. It was a PIA doing the front shocks and could not imagine doing yourself at home on jack stands.
