  1. Very nice kit! - Posted by: Speed Bump (4/27/15)

    My only complaint is when I went to bolt the brake hose back to the top of the spindle the tapped holes were too close to the ball joint to bolt it back on! Just made a little bracket to relocate it! Other than that it's a very nice kit! Spindles are raw metal.. Shot the with a littl rattle can paint and they were good to go! All the other stuff was powder coated and seem to be good heavy gauge metal! I was very pleased lol! I have a 2004 GMC Sierra 4 door with 22's! I chose this kit because when I can afford a lower profile tire I plan on going lower! With this kit having a flip kit for the rear that will be easily done! And just add a spring to the front and your closer to the ground!
