This bolt on 4link center cradle consists of 4 pieces to create a box shape sub frame under the truck. We use 1/4" thick steel for the outter side pieces and then we use 7GA (.187") on the front and rear to tie it all together to make a box. This cradle will accept any heim that is 2-5/8 wide with a 3/4 bolt. Face plates and harware are included and will ship raw. (No Coatings)
