Radius arm angle, need info.
Ok, so i put a 6" skyjacker suspension lift into the ol girl. 79 F150 4x4. I bought all the goodies to do it right. Drop pitman arm, track bar bracket, and radius arm drop brackets. now i knew it would drop the arms down a bit, but it seems like i either dont have enough lift in the front, or the brackets were overkill....My arms are sitting almost dead level, or maybe even sloped up a bit going to the axle....what is the ideal radius arm...angle shall we call it? I just want everything in the front end to be strait and true, thats why i spent the extra money for the parts. Thanks for any and all help guys

There has never been anything printed as to prefered angle.(as far as I know).When rad. arms are moved up/down the caster angle will change,most trucks have 2-4 degrees.By dropping the arms more then the axle it creates more possitive caster,some kits give new C-bushings to keep it where it should be.Chances are that the drop-brackets are also used for an 8" kit,which is why they are a little longer on yours.The drop brackets also help to keep axle centered in wheel opening,3'' kits don't need-em,4'' do,and so on.It's not hurting anything like it is though.You can probably get the drop-brackets for a 4'' and be good.I had a 79 also,and I accumulated a bunch of parts before I lifted it and used 4'' drop brackets and 6'' springs and never had a problem.

mhmmmmm....mhmmmmm, i thank both you fine gentlemen, i will have to take a good look at er when i can get it back in the shop. Im not sure i can just drill another hole, but maybe shorten them up a bit or something like that. My radius arms with the truck level will be a few degrees sloping down from the axle....looks funny to me, but unless for some reason im not getting the lift in the front like i should, it cant be all totally wrong.

i am having this same problem i have pics in my gallery to show the exact same thing. i am thinking about buying the 9" lift springs just so it doesnt look so stupid. what would happen if i lifted a truck 6" w/o the drop brakets?? it it looks like too much on 6" lift what would be the down side effect of it???
