SPC Dodge Ram 1500 Ball-Joint part # 23940.
Its an offset balljoint that allows precise adjustment.
"If your Dodge Ram 1500 has been lifted or lowered you may not have enough factory adjustment range to properly align your truck. This Specialty Products Company upper control arm ball-joint is designed specifically for use on Dodge Ram 1500 series trucks built on the 5-lug chassis. This item will NOT fit Mega Cab models! With this ball-joint you can gain up to 2.0 degrees of camber or caster. Simply replace the ball joint in the factory stock upper control arm to get plus or minus 2.0 degress of caster, camber, or a combination of the two. You can then perform the final adjustments using the factory alignment cams."
