CB Engineering Front Strut Spacer Plates for Jeep WK Grand Cherokee / XK Commander vehicles. We now offer these in two different lift heights. Standard lift, using 0.25" steel spacer that give roughly 0.5" of lift in the front of your Jeep. New, extended lift, using 0.375" 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 come with our 2 Stage powder coat for a long lasting finish.
