    Caster angle is the angle in degrees of the steering axis in either a forward position (negative caster, bad) or in a rearward fashion, IE the top of the steering axis is rearward of the bottom of the steering axis. This is positive camber, which is what you want. Has nothing to do with shock absorbers..

    So should I have 2.5" lift all around with 32" tires? would that level the jeep out more since its raking now in the front? My front springs look flat right now, and I ordered replacement (7 leaf), put the fenders on temporarily so see how the body fits with all my body work I've been doing, but seems like with the flat springs I have on there now, it may rub my tires when I hit a big bump. Pic. is coming.. I just want to know if the 2.5" leaf kit will give me more room.

    These are with the "flat leafs" on there now. and you see the shackle on the one photo, looks like it could be adjusted as well. suggestions on leaf springs? 2.5" yes/no?

    M38A1 did the same, with the extra plate OEM. Or at least my M38A1-C did.

    Patrick, so I was putting my new shackles and 2.5" skyjacker springs on the front of my 66. My shackles on the front springs are on the back side of the springs, I believe reverse. but the shackles / caster angles are pointing forward which should be pointing back correct? How do i correct that?

    Caster angle is not the shackle angle. It is the angle of the wheel pivot wrt vertical.

    Length of the shackles will change the caster angle, but they are not the same.

    Im sorry, i was reading our previous statements and was thinking caster, but meaning shackle angle.

    My springs are the same size from eye to eye, the new shackles are replacing my old ones because they were old and wore out. but in the picture above my shackles are pointing backwards and hitting the frame, my new ones are pointing frontwards at about a 20 degree angles and the midpoint where the axle sits on, is off about 1' -1.5' from center. what is going on?

    No. Thinking if I put weight on it it will fold More inward toward engine/front end. Haven't even got the axle lined up. It's off an 1"-1.5".

    As the spring compresses, it gets longer. The shackle will move back. Nothing can be determined until it has weight on it.
    What you have there is exactly what I would expect.

    got them on there, the axle is tight to get into the pin hole. I dont see it sitting any higher though. I know the leaf springs on my jeep go under the axle because there is no slot on the top for the leafs pin to sit in. Seems like the 2.5 lift suspension did no justice to my 66 cj5 for right now.

    Should there be a shackle hanger or mount on the frame? Looks on my small screen phone that the shackle is mounting directly into the frame. I know you said reversed shackle but seems odd. Or am I just blind?

    so these images are my front suspension. On the images i sent the shackle is on the back side of the leaf springs. and the stationary spring hanger is on the front, which is not shown. the image you see James is the U shackle or I call it the C shackle which is grease-able shackle original on my 66.. I replaced it because they were beat to hell.

    You may be very well be right...but I would think there would be a 'stationary' hanger on the rear as opposed to mounting directly through the frame (is the frame boxed there?) - I will readily admit that I am not personally familiar reverse with shackle set-ups - but I still thought there was some sort of 'eye' mount welded on the frame for the shackle or spring eye no matter which end is forward (kind of like some of the earlier pics . Or is it because the frame rails step down between the frame horns and the rear spring/shackle mount that a dropped down (on the underside of the frame rail) 'stationary' mount is not needed and it goes through the frame. Those that know can chime in ... good luck with it...

    so where the old shackle in the original pic w/ the two grease zerts, the one in the frame has a solid sleeve through the frame. so I mounted the new shackle through that sleeve. I think that is right and the stationary hanger is near the front bumper. I hope it right..yes ayone please chime in.

    James i think i know what your're talking about. a pivot hanger on the back side. I think I am going to add one to all leafs. Think this will allow another inch in the lift as well.

    I've been wondering the same thing, I put a Rough Country Leveling kit on the front of my 03 Ram 1500 quad cab 2 years ago, which was a set of torsion bar keys and new shocks to get the nose up higer for a snow plow frame . I realize it's a apples and oranges comparison (torsion bar versus leaf spring) but quality was spot on and the instructions were very thorough so I plan on using their kit on my CJ 5 31x10.50's is plenty high for me. T.J.
