11-19 trucks did not come with an OEM steering stabilizer, however there are mounting provisions to add a steering stabilizer. Adding the Cognito pitman and idler arm support kit removes the need for a steering stabilizer and offers more benefits than the stabilizer does. For customers who wish to use both the Cognito Pitman Idler Arm Support Kit and a steering stabilizer must use this mounting kit to drop the frame mounting end of the stabilizer down to clear the Pitman Idler Arm Support Kit brackets.
