Seven, my original comment was meant to be somewhat tongue in cheek. Obviously, there are thousands of knuckle lifts out there that more or less work. Now, I am not trying to be a smartass, but aren't you proving my point with the fact that Cognito is the only one doing this, shall we say, "right"? There is nothing inherent to the lift knuckle that is bad. (Well the track width but never mind.) The point is the reason why all these lifts use the lift knuckle, they skimped on dropping the diff. If I decide to crank my tbars, its with the understanding that there are certian negative aspects to doing so. These kits have those negative aspects built in.
Now as far as RCD specifically, well all I can say is I got to see the three sets of tie rods that one truck with a RCD lift( +3 body) went through in little over a year. All on the road with 36 inch tires. One more inch in tire height can't make that much difference. Last time I related this to someone they told me that who ever installed the lift must not know what they are doing. I don't know BD, what do you think? Does Gene and his crew know what they are doing or not?
