The Center Line I.C.E. 17-inch wheels are the easiest bead locks we've ever assembled. All it took was a torque wrench and an Allen wrench, and we had each wheel together in under 12 minutes. You can replace the inner piece of the modular wheel to change lug pattern and variable offset. They weigh about 40 pounds each, and each one costs more than the BFG Krawler they're mounted in, but they are so worth it.
