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 0.375" 304 stainless steel spacer that give roughly 0.75" of lift. These the thickest spacers you can run without running out of threads on the factory upper mount. 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 a little 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.
