Do these come with the bushing like in the pictures?
C G March 2, 2019
Yes, these will come with the new bushings already pressed into the arm.
Ian P March 2, 2019
The bushings are pre-installed in uppers and lower control arm mounting bracket, as shown, and the upper and lower ball joints are included in the set. Cheaper than having just the bushings replaced in my blazer!
