It does have a 2 inch lift . Polybushes etc plus the tyres.....it has about 14 inch clearance under the tanks. ..is this not sufficient clearance for general stuff? ThanksI had two under tanks on my disco. Absolutely ****e off road with them on, you go over a bump and its scraping on the ground. Not a good idea. If you want to take it off road, scrap the tanks.
Sounds like you should check the quality of the mounts. I never was troubled with mine but I did have rock sliders. They still took plenty of scrapes and bangs, did a few rtv trials with them
