yes there the ones, (sorry I didn't see the link) I used them for about 2 years before I sold the disco and had no issues whatsoever :)

you can buy 2" lift blocks that sit between the axle and the spring saddle, I had them on my old discovery which already had lift springs fitted so gave it a 4" lift, look smart, and had standard props though did have to change the radius arms. you can buy the blocks on eBay for about £35
