These are adjustable rear lower control arms, to be used on any vehicle lifted or not, up to 4" of lift. This kit comes with both side lower arms. Rubber bushings now come pressed into the arms, as they are maintenance and noise-free. Rubber bushings allow for greater flex (travel). These adjustable arms will allow you to properly set your front pinion angle due to adding a lift, while also adding strength over the stock arms. Suitable also for long travel rear suspension setups.
NOTE: The threaded end goes towards the frame end with the curved section on the inside.
