This product performs well, I didn't expect it to be as big and heavy as when I opened the box. Most reviews advertise easy setup, if I did it a second time I'd agree but the instructions don't really help you set this up - it's a good tricep workout nonetheless. Lying on my back trying to reach my head to raise it, as well as the stabilizer bar to hold them in place and even tightening just one of the screws was a problem for me. I found tips in the forum. to hold up the anti-roll bar (no anti-roll bar) with the screw on the passenger side, then lift the anti-roll bar and pass the rear driver's screw through the anti-roll bar and the anti-roll bar, then pull out the screw on the other side and complete the installation. It makes it so much easier. A few other points in the documentation: the connecting rod bolt doesn't match the size listed in the docs, and good luck finding a socket deep enough to fit, unless you're working with heavy equipment. The large crescent key worked, but I spent the money on an outlet I didn't need. Finally, there are conflicting recommendations as to whether the lock washer should be retained. When I look at the picture in the instructions I don't see it but I read that it is required. I installed the whole thing with a lock washer only to find I didn't have enough clearance so I had to take it off again, remove the lock washer and put everything back on. All of this suggests that the difference is obvious. It's a lot easier to stay in lane, and the steering is firmer and more responsive. This is a much more substantial product than I thought I would get for the money, overall I'm happy with it.
