Bought these about 3 months ago, decided to swap out the winch so don't need such a heavy duty shock anymore. It's meant to support 200 lbs+ constant front load. If you have a front metal bumper or a winch or both then this is your shock. Had about 500 miles on them(damps really nice). Already put together so no need to compress the spring or any of that extra hassle. Take your old shock out , put this in. Fits 03-09 4runner and all fj cruisers. Lowest online price is 520. My loss your gain.
