Firstly, this adapter has an internal width of 35mm. TJ shock bushing width is 39.5-38.0mm. You simply cannot install a shock absorber in this mount. The second problem is that the included 3/8" screw doesn't fit the threaded hole in the adapter. It looks pretty solid, but useless if you can't fit shocks. Screws won't screw in. Good concept, but bad ones Execution Do not buy.
