These traction bars are made from 7ga (.187 thick steel) and come complete with our rear buckets that will replace the factory style so you wont have to weld any tabs to your axles. Front frame mounts are included and can either be bolted on or welded. Both ends will have a Prothane bushing. Harware is included and will ship raw. (No Coatings)
