These are 1/2 inch top plate spacers. They go right on top of your existing strut or coilover. These will give you 3/4 inches of lift. This is a great way to get more lift out of your factory suspension or add a little more to any aftermarket lift you currently have. These are also great if you want to run them with coilovers to alleviate some preload and soften up the ride. Asking $45.
