    He was asking if it was parallel to the LCA, not if the angle looks bad or good. Yours do not look parallel to the LCA. Mine look parallel to me. What all this has to do with alignment I dunno.

    On solid axle rigs, like the 2500 4x4 rams, when the track bar and drag link are not parallel, they have bump steer.

    it's the same thing with the 1500's, but on a smaller scale.
    On the 2500's, if the drag link and track bar are not parallel, both tires will steer left or right as the axle moves up and down.
    On a 1500, if the tie rod is steeper than the control arms, as the suspension drops, the tires will toe in. When the suspension compresses, the tires will toe out.


    Anyway, got the truck back on Friday, and all seems well. the alignment is back in spec (although, I'm still going to keep a really close eye on the tire wear), and they said that the ball joints and bushings all checked out great.

    After getting it back though, the tie rod angles seem to be much more parallel to the control arms than I remember. I took some pictures last night, I'll post them in just a bit.

    However, after seeing all of your pictures, I'm beginning to wander if I have a 4" or a 6" lift?

    Here are the pics of my angles.

    And here’s an overall for an idea of height. Tires are 35’s, think it’s a 4” or 6” lift??

    I cant tell from the underside, but looks to be a 6" lift from the last two pics. My cv shaft angles have me worried. It is extreme in comparison to everyone else.

    Sorry for using the wrong terminology but they’re pretty dang close to parallel. Tie rod might have a very slight more of a angle, hard to tell crouching under the bumper trying to take a pic and not sitting perfectly level in the driveway, but nothing bad by any means. Again look at the boot on the spindle, not smashed and pretty even spacing all the way around.

    I see nothing to be concerned about, looks fine to me.
    Yours might be a 4" kit, look at the negative angle on your UCA versus blackbeauty's UCA angle of his 6". Your CV's are also at a negative angle versus his almost flat.

    I bought it used with the lift already on it, that’s why I’m not sure if it’s 4” or 6”.

    Here’s what I do know though:
    1: It “appears” to have non-factory upper control arms on the rear axle. From what I’ve been able to find, only the 6” comes with new arms. Although it is possible that the arms were swapped out separately.
    1a: it does not have the stainless extended brake lines that now come with the 6” kits. Instead, it uses drop brackets for the factory lines.

    2: the drop brackets for the lower control arms lowered the arm mounting points by right at 4”.

    3: the strut spacers are 5.25” tall.

    4: the front has sagged a little bit sense the installation of the 12K winch.

    5: before the winch, the fender heights were approximately 42” all around. (I’ll measure it later today and report back)

    Just ran out and checked fender height.
    Rear is still at 42”
    Front is 41”

    1. your correct must be a 6"

    1a: Looking online at "what's in the box" and "installation instructions", Rough country does not include stainless brake lines in the 4 or 6" kit, where did you get that info?

    http://www.roughcountry.com/dodge-suspension-lift-kit-324c.html

    3. If the spacer is 5.25", and the preload is approx. 1" according to blackbeauty so that’s right at 6” lift

    I could have been mistaken about the brake lines. Thought I remembered reading somewhere, that they were now included, but can’t seem to find it now.
