CB Engineering Front Strut Spacer Plates for Jeep WK Grand Cherokee / XK Commander vehicles. We now offer these in three different lift heights. Enhanced lift, using 0.5" 304 stainless steel spacer that give roughly 1.0" of lift. These spacers will cause you to run out of threads on the factory upper mount. We recommend pressing out the old studs and putting bolts in place of the stud. These slip over the top of the strut plate. They do not require dis-assembly of the front strut. Simple bolt on installation. This is a nice way to add some boost to the front of your Jeep to get a more leveled look. These are made from 304 Stainless Steel plate that will not rust and will last a lifetime.
