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 also the deeper model, made for wider frames, these are 2 3/8" deep when measured from the outside face of the frame towards the engine compartment. All of our shock towers are 1/4" 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 complete with Grade 5 Nuts and Bolts, we use Grade 5 over Grade for the flexibility, Grade 8 will shear when Grade 5 will flex.
