Blocks are an easy way to add height to a vehicle without increasing spring rates. Only use on rear axles with vehicles using a spring-over axle design. U-Bolt kits include four U-bolts and nuts and are available in various diameters and lengths.

I recently purchased 3.5" rear spring packs from 4wheel parts (within the last month)and they came with degree shims built in, they have since sagged below the desired 3.5", my question... can this spacer block kit be safely used under/with the degree shims to regain the height lost.
