These are the shortest of the Shock towers we make, most vehicles will fit a 10 - 12" coilover with these. And no, they are not hoops! These are 9 3/4" above the frame at the shock mounting position center. They are 15 degrees offset from the frame. These are 2" deep when measured from the outside face of the frame towards the engine compartment. All of our shock towers are 3/16" thick and come in pairs. You must choose what width of mountinng eye for us to provide, 1 1/4", 1 1/2", or 1 3/4". Measure your shocks with any missalignment to determine what width you want. These come in pairs complete with Grade 8 Nuts and Bolts.
