Certain lki enterprises, Inc., brand name superlift suspension, pitman arms sold as replacement equipment for 2003-2007 Dodge Ram 2500 and 3500 4X4 light trucks. Due to inadequate heat treatment during production, the affected pitman arms may develop cracks in the upper splined attachment attachment to the steering output shaft. Movement between the pitman arm and the output shaft may deform splines, resulting in premature wear and fatigue failure of the affected pitman arm.
