Yes, sort of. I found the expensive, cheap, and middle of the road options. Cheapest was 50mm springs from Pedders. The "Heavy Duty" 50mm springs from KingSprings are not yet available (but very soon I'm told).
The medium price option was custom shock mounts and using true racing adjustable long travel coilovers.
The most expensive option was to either:
1. Use racing coilovers, topped with an airbag for ajustable lift (www.universalairsuspension.com), connected to a controller, compressor, tank, etc..
2. Purchase factor air shocks and add an aftermarket controller, compressor, tank, etc.., most likely from this company here: www.roverspecialties.com
Funding being an issue, I went with the simple 50mm spring lift It's being installed tommorow!
