While we recommend extended shackles or replacement springs for any vehicle that sees serious off-road use, lift blocks are a viable and inexpensive option for adding a little more rear lift. Rusty's 2" steel lift blocks are fabricated from 1/4" thick steel and fully welded, making them much stronger than cast steel or aluminum lift blocks. In addition to the exterior structure, there are internal reinforcements that render these blocks virtually indestructible. If you have an application that needs lift blocks, these are the ones to use!
