    Took 3 weeks to get here even during this virus!! Very satisfied and ride amazing, makes my z look good

    Pretty dang neat

    I don't know why I didn't buy these earlier. Finish and build quality are both equally amazing. Good ride quality, even for 18k springs. My only complaint is that they don't go as low as I had hoped, even with the extreme drop kit (but don't get me wrong, they will get you really fucking low if that's what you want). Picture was taken right after installation with all four corners maxed out.
