The supplemental aftermarketair springs are a great!
idea. Iinstalled them on my Grand Cherokee so I could carry my 270# dirtbike ona hitch mounted rear carrier (just hangs off the back across the vehicle)...made a huge improvement in how the vehicle handles with that much weight hanging off the hitch. I've even had a 520# sportbike back there with no problems. The carrier itself weighs 80#, so that's 600# total...good thing the maxtongue weight is 750#. Before Installing them I drove 250mi with the dirtbike on the back of the Jeep and it was pretty hairy at times. With the air springs you barely notice the extra weight back there.
Go to www.airliftcompany.com
for more info. However, they do not list Land Rover in thier catalog, so I made an enquiry and they told me if I measure the coil springs they may very well have some air bags to fit inside but that they would not offer a warranty since they do not list them in the catalog. I'm guessing they'd probably be fine and that they just haven't tested the application...Land Rovers aren't so common.
I will definitely be installing them on my Discovery after I swap out the onboard compressor and gauge from the Jeep. I would go so far as to say these are a must!
if you are planning on towing some weight.
Though I'm a little dissapointed in the lower 551#max tounge weight of the Discovery...the hitch design does not look as strong as the Jeep's hitch, but should be fine for the dirtbike. Though I'm hoping to carry a 470# sportbike on it...I'll be right at the max [sm=smiley3.gif]
