Bulletproof M.O.R.E. motor mounts allowed the new GM GEN III 5.3L V8 to fit easily in the YJ's engine compartment. Advance Adapters supplied pretty much everything else to make this a painless project. Howell Engine Developments works with Advance Adapters and supplied the OE-quality wiring harness and computer. All sensors were utilized, and everything works like it does from the factory in a GM truck or sport ute. Rockworx built the coilover mount bridge and mounted the reservoirs from the Walker Evans Racing coilovers there. This made the reservoirs get too hot, so they've since been moved. An Optima YellowTop sealed gas recombinant battery was installed for reliable power.
