Most vehicles will fit a 12″ – 14″ coilover with these. And no, they are not hoops! These are 12″ 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 mounting 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 in pairs with Grade 8 Nuts and Bolts.
