Cognito is better than most because of their supporting options that can be added to their kits. I run the 9-11" kit on mine and it is a very durable kit from an engineering standpoint. Their tubular upper control arm is awesome and takes the harsh angle off the upper ball joint, and you can also purchase the heavy duty tie rods and idler/pit man arm braces. They basically cover all of the weak points with their kits. I have ran fabtech and rcd before with no prob in the past, but the cognito kits are far more durable and by far the best IMO .
