In general, the installation took an hour and a half at most. This is given that I take my time and get the right tools, clean the threads etc. I am happy with my purchase. I noticed less steering play, tighter corners and less road drift. It fit easily on my 1999 Dodge Ram 2500 4x4 Cummins. SCREWS AND HOLES MATCH. All hardware was fine. Cons - No installation instructions included. I want the welds to be complete, not partial. I'm sure everything will be fine, but I'm an overkill, persistent guy on a tight budget. Also, I don't think screws are class 8. But they do what they were designed to do. Tip - I recommend a second pair of hands to help install the anti-roll bar and anti-roll bar. Good and complete ratchet set with 1/2 and 3/8 drives and a complete set of sockets. Possibly a medium or large cresent wrench, good penetrating oil and if possible an adjustment rod and torque rod. INSTALLATION - step-by-step instructions in pictures. The last picture is a complete installation. Hope this helped! I definitely recommend this product.
